YDTech® manufacturer of support rollers, cam followers (NATR, NATV, NUTR, NA22)needle roller bearings! supplier of stud type yoke track rollers(KR, KRV, KR.PP, NUKR)bolt gyro, curve type wheel, needle roller bearings in china.

roller follower bearing (KR, KRV, KR.PP, NUKR) needle roller bearings (NATR, NATV, NUTR, NA22) are thick walled outer ring, with high-temperature high-nitrogen quenching , high-precision roller separation of the outer ring by the high rigidity of the wall to guide the use of linear contact wheel can rotate in the roll along easily and can withstand the tremendous load.

to remove the stress, the outer wheel support the use of Globoidal design, curves have with single wheel, dual-ring, non-ring, sealing ring with a variety of model specifications. Grease storage ring with a large space, they provide long-term lithium grease lubrication, and extended lubrication intervals.

bolt gyro wheel (needle roller bearings KR series, KRV series, NUKR series bolt-type needle roller bearings by the axle bolt G20CrMo. effective from fine 1.3mm hardened layer, and then by the group as a roller rolling road bolts and a combination of thick-walled outer ring. Shoulder bolt axis and the pressure in the bolt face on the composition of the outer ring along the two sides of the direction of the guide surface. When the curve of the wheel in the flat raceway or cam plate on the sport, as a result of elastic deformation of the outer ring, the inner wheel to increase stress. applies to such work is therefore under the curve of the rated load wheel select a column:

bolt gyro bearing and curve rollers are ready to install units, consisting of a roller bearing with a thick walled outer ring that can withstand both high and shock loads. rollers are based on deep groove ball bearings or angular contact ball bearings while bearing and curve rollers, are based on needle roller bearings or cylindrical roller bearings. curve rollers have a massive bolt, which is fitted with a thread, so that they can quickly and easily be attached instead of an inner ring.

cam followers instead of an inner ring, cam followers have a solid stud that is threaded so that the cam follower can be quickly and easily attached to appropriate machine components by means of a hexagonal nut.

our support rollers have an internal design based on needle or cylindrical roller bearings. They have a thick-walled outer ring, which enables them to accommodate high radial loads, while reducing distortion and bending stresses.
