Cylindrical Roller Bearings for Radial Load Applications

Shandong Hongchuang Bearing Co., Ltd. produces cylindrical roller bearings and related bearing products in Shandong, China. Its cylindrical roller bearings are separable bearings: the cage, roller and guide ring form an assembly that can be separated from another ring. This makes installation and disassembly easier, especially when the inner and outer rings have an interference fit with the shaft and housing.

The rollers are usually guided by two ribs of a certain ring. The bearings are generally used to bear radial loads. Only single-row bearings with ribs on both the inner and outer rings can bear small constant axial loads or large intermittent axial loads. Compared with deep groove ball bearings of the same external dimensions, they have a larger radial load capacity.

The main structure types are N with no ribs on the outer ring and double ribs on the inner ring, NJ with double ribs on the outer ring and a single rib on the inner ring, NU with double ribs on the outer ring and no ribs on the inner ring, NUP with double ribs on the outer ring and a single inner rib plus one piece, and NF with a single outer rib and double inner ribs. Cages can be stamped or nylon, and some models are full complement without a cage.

Cylindrical roller bearings generally do not allow the shaft to tilt relative to the housing bore. For single-row bearings under light load, the inner and outer rings may incline 2 minutes of arc, and under larger load the allowable error is slightly more but not more than 4 minutes. Different tolerance classes are available, and the machining accuracy of the shaft and housing should be checked.

Double-row cylindrical roller bearings have a small cross section, high load capacity and high rigidity. They are used in machine tools, rolling mill stands, plastic rollers, grinding machines and large gearboxes. The NN and NNU types are available with cylindrical or tapered bores, and some have lubrication grooves and holes in the outer ring. Payment terms are T/T, 100 percent L/C, cash or Western Union, and delivery is about 30 days.

For cylindrical roller bearings, buyers should confirm the structure type, the bore and outside diameter, the tolerance class, the cage, the clearance, the lubrication and the load direction.
