SL type double row cylindrical full roller bearings (SL type cylindrical roller bearings) are usually composed of a combination of two guide edges of a bearing ring, a cage, rollers, and a guide ring, and are generally separable bearings. This type of bearing is relatively easy to install and disassemble, especially when it requires interference fit between the inner and outer rings and the shaft and housing, which highlights its advantages. This type of bearing is generally only used to withstand radial loads, and only single row bearings with both inner and outer rings with ribs can withstand small axial loads or large intermittent axial loads. Compared with deep groove ball bearings with the same external dimensions, SL type double row cylindrical full roller bearings have a larger radial load capacity and are also suitable for high-speed rotation from a structural perspective.

The SL type cylindrical roller bearing models are as follows

Both cylindrical rollers and raceways are linear contact bearings. High load capacity, mainly bearing radial loads. The friction between the rolling element and the ring flange is relatively small, making it suitable for high-speed rotation. According to whether the ring has a blocking edge, it can be divided into single row cylindrical roller bearings such as NU, NJ, NUP, N, NF, and double row cylindrical roller bearings such as NNU, NN. This bearing has a separable inner and outer ring structure. Cylindrical roller bearings with inner or outer rings without retaining edges, where the inner and outer rings can move relative to each other in the axial direction, can be used as free end bearings. A cylindrical roller bearing with dual gear edges on one side of the inner and outer rings and a single gear edge on the other side, capable of withstanding a certain degree of axial load in one direction. Generally, steel plate stamping retaining frames or copper alloy solid retaining frames are used. However, some use polyamide molded retainers.
