take advantage of this outer ring

urve 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 rollers 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 slewing bearing 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.
