Spherical outer ring can make use of the tilt position when installing compensated

Curve of the wheel bolts as part of the raceway is hardened. To avoid stress concentration, thick-walled outer roller surface arc-shaped out of the loop. Curve with two angular contact ball bearing single and double seals, without seals, with seal ring a variety of models. Grease a large space with a storage ring, providing permanent lubrication, and extended lubrication intervals. N220 or PTFE gasket material for its operating temperature ranges of -30 ° C to +100 ° C or -30 ° C to +180 ° C. Dense loading curve wheel it can withstand heavy loads, but the speed is low, and it must always be lubricated.
Supporting roller has thick-walled outer ring, take advantage of this outer ring, the wheel can roll in the raceway, and can withstand large loads. VG-bearing roller pressure roller, eccentric roller, roller rocker. Wheel diameter cylindrical or spherical. Spherical outer ring can make use of the tilt position when installing compensated.
RSTO and STO-bearing rollers
DF-Series RSTO type roller bearing without inner ring, roller bearing can be directly used as a raceway shaft quenching operation. STO-belt inner ring, with its inner and outer rings and needle roller cage assembly can be installed separately. As RSTO and STO-bearing roller ring without ribs and the end, the installation must have axial guidance, its guiding surface is at least precision lathe.
RNA22 ... 2RS, NA22 ... 2RS-bearing roller
This wheel diameter wheel with STO same series. They just slightly wider, double sealed structure makes no maintenance, use temperature range is -20 ℃ -120 ℃. Installed without inner ring RNA22 ... 2RS series of roller bearing should pay attention not to damage the seals. Outer boot needs to end.
NATR and NATR ... PP-bearing roller
NATR series of roller bearing includes an outer ring, inner ring, roller cage assembly and pressed into and fixed to the inner side of the ring. NATR ... PP series also additional sealing ring. The wheel bearing grease with a large storage space, long-term use without greasing.
