The DAC series represents the most widely used first-generation hub bearing unit, featuring a double-row angular contact ball design arranged back-to-back (DB). These bearings utilize integrated inner and outer rings and incorporate double-sided rubber seals; they are pre-filled with specialized grease and have preset axial clearance at the factory, requiring no adjustment upon installation. Utilizing steel balls as rolling elements—which maintain point contact with the raceways—the series achie...

The UCPH series is a high-center variant of the UCP pillow block; the shaft center height (the distance from the base bottom to the shaft centerline) is greater than that of the standard UCP. High-center housings are selected when the shaft needs to be elevated above the mounting surface or when clearance is required beneath the shaft for other components (such as other shafts, piping, or mechanisms). The pillow block Bearings are essentially a variant of deep groove ball bearings; they are cha...

The UCPA series is a narrow-profile variant of the UCP pillow block unit. Featuring a narrower base width than the standard UCP, it is designed for applications where installation space is limited and the available width cannot accommodate a standard housing. These units typically utilize stamped steel or narrow cast iron housings; consequently, load-bearing capacity is reduced, making them suitable for light-duty applications. Pillow Block Bearing is a bearing unit combined roller bearing and...

The UCFC series features a circular flange with a central pilot (locating boss). During installation, the pilot fits into a corresponding locating hole on the equipment panel, ensuring precise coaxial alignment. Secured by four bolts, this series is suitable for drive applications requiring high coaxiality and precise positioning. The pillow block Bearings are essentially a variant of deep groove ball bearings; they are characterized by a spherical outer diameter surface on the outer ring, allo...

The UCT series, also known as take-up bearing units, features guide slots on both sides of the housing, allowing for axial sliding along the rails of a matching frame. These units are primarily used in the tensioning systems of belt and chain conveyors; by adjusting the position of the bearing housing to alter the shaft center distance, the tension of the belt or chain can be regulated. The pillow block Bearings are essentially a variant of deep groove ball bearings; they are characterized by...

The UCFL series features an oval (rhomboid) flanged housing secured to a vertical mounting surface via two bolts. Compared to the square-flanged UCF series, the UCFL is smaller, lighter, and requires less installation space, making it ideal for light-duty applications where space is limited. The pillow block Bearings are essentially a variant of deep groove ball bearings; they are characterized by a spherical outer diameter surface on the outer ring, allowing them to fit into a corresponding co...

The UCF series features a square flanged bearing housing that is secured via four bolts to a mounting surface perpendicular to the shaft (such as the side wall of a machine or the end face of a housing). The bearing axis is perpendicular to the mounting surface, making this series suitable for applications where mounting from beneath the base is not possible and the shaft must be secured from the side. Pillow Block Bearing is a bearing unit combined roller bearing and housing together. Most of t...

The UCP series represents the most versatile and widely used standard product line among pillow block bearings. These units feature a vertical, rectangular-base housing secured by two bolts to a horizontal mounting surface parallel to the shaft, supporting the rotating shaft from below. They are supplied ready-to-use, with the insert ball bearing already pressed into the cast-iron housing and pre-filled with grease and seals. UCP series housed units feature the set screw locking (UC) bearing ins...

The 6900 series deep groove ball bearings belong to the thin-section category of single-row deep groove ball bearings, often referred to as the "extra-light series" (note: while the 6000 series is also classified as extra-light, the 6900 series is even thinner). Model numbers begin with "69," such as 6904, 6905, 6906, etc. The cross-sectional dimensions of the 6900 series fall between the thin-wall series and the standard series: the outer diameter is larger than that of the 6800 series but smal...

The 6800 series deep groove ball bearings belong to the thin-section category of single-row deep groove ball bearings, often referred to as the "extra-light series." Model numbers begin with "68" (e.g., 6804, 6805, 6806). The 6800 series serves as the "mainstay" of thin-section bearings: it is more practical than the 6700 ultra-thin series and lighter/thinner than the 6900 series. Widely used in applications requiring space efficiency, light loads, and high speeds, it is the most commonly utiliz...

The 6700 series represents the ultra-thin-walled category of single-row deep groove ball bearings; among all standard deep groove ball bearings, this series features the thinnest cross-section, the smallest outer diameter, and the narrowest width. Model numbers begin with "67" (e.g., 6704, 6705, 6706). The 6700 series is designed for extreme applications: providing rotational support in environments with severely limited radial space, very light loads, and extremely high rotational speeds. It i...

The 6400 series represents the "heavy" category within single row deep groove ball bearings; it features the largest cross-section and the highest load-carrying capacity among all standard deep groove ball bearings. Model numbers begin with "64" (e.g., 6404, 6405, 6406). The 6400 series boasts the largest cross-sectional dimensions of any deep groove ball bearing series, characterized by the largest ball diameters, the highest number of balls, and the thickest rings. The 6400 series is position...

The 6300 series deep groove ball bearing belongs to the "medium" category of single-row deep groove ball bearings—often referred to as the "heavy series" (in comparison to the 6200 series). Model numbers begin with "63" (e.g., 6304, 6305, 6306). The positioning of the 6300 series is clear: it is the step-up choice when the 6200 series is insufficient for the load. It trades higher volume and lower rotational speeds for superior load-carrying capacity. While the structural design mirrors that of...

The 6200 series deep groove ball bearing belongs to the "light series" of single-row deep groove ball bearings; it is the most widely used, highest-volume, and most representative series among all deep groove ball bearings. Model numbers begin with "62" (e.g., 6204, 6205, 6206). The structure of the 6200 series mirrors that of other single-row deep groove ball bearings, consisting of four main components: the inner ring, outer ring, steel balls, and cage. Options include ZZ dust shields or 2RS...

The 6000 series deep groove ball bearing is an "extra-light" series within the single-row deep groove ball bearing family; it features the thinnest cross-section and the smallest outer diameter among all deep groove ball bearing size series. Its type code is "6" and its size series code is "00" (width series 0 + diameter series 0); consequently, the full model number begins with "60" (e.g., 6004, 6005, 6006). Within the deep groove ball bearing family, the 6000 series is renowned for being "lig...
