1, NNF ... ADA2LSV / SL04 double row full complement cylindrical roller bearings: two inner ring, two inner joins the clamp ring together, can not be separated, the outer ring has a wall, can withstand a two-way axial load, used for locating bearings. Due to the large distance between the two rows of rollers, but also withstand the overturning ferris wheel bearing moment. Outer surface has two retaining slots, can the axial positioning. This type of bearing is equipped with contact seals on both sides, built lithium grease, operating temperature is limited to -40 ℃ ~ + 80 ℃. Under certain conditions, this type of bearing no maintenance, but when there is moisture or contaminated run-time, and often for medium-speed or high-speed running, you must add lubrication. In the case of using oil lubrication, seals to be removed and cleaned of grease within the conical bearing, turn the 30% increase when using oil lubrication.

2, NNC / SL01 series full complement cylindrical roller bearings: for non-sealed bearings, the outer ring of the overall split by locking plate connected together, so the outer ring can not bear axial load, outside the subdivision after is exactly the same circle, each with a wall that can be positioned axially in both directions. Inner ring with three ribs. The outer ring with oil groove and three lubrication holes, this series is usually oil-lubricated bearings.
3, NNCL / SL02 series Full complement cylindrical roller bearings: for non-sealed bearings, outer wall with oil groove and three lubrication holes. miniature linear bearings Inner ring with three ribs. A fixed outer ring provided with the center between the two rows of rollers, the rollers can be prevented from falling out, maintaining the bearing as a whole. This series bearings can allow a certain axial displacement occurs within the bearing between the shaft and the bearing. Because as a floating bearing end
4, NCF ... V / SL18 type full complement cylindrical roller bearings: a single outer wall, no wall side has a lock ring can be unidirectional shaft positioned inside the bearing axial clearance "S" with respect to the shaft ensures that the axial positioning of the bearing box moves.
