NMT Cam Follower Bearings High Precision Wear-resistant Heavy Load Cam Follower Bearings For Automatic Production Lines And Machine Tool Conveying Equipment
Automatic production lines, packaging machinery and stamping equipment are widely equipped with cam transmission and guide rail circulating conveying mechanisms. As core moving parts, cam follower bearings keep reciprocating friction against guide rails and cam surfaces. Conventional roller bearings feature thin outer rings, prone to deformation and surface indentation under impact loads, resulting in surface spalling failure after long-term cyclic operation.
Many machines perform high-speed intermittent reciprocating motion. The running stability of bearings directly affects processing and packaging precision. Production lines operate nonstop all year round. Limited assembly space makes frequent bearing replacement lead to costly shutdown losses. Dust and cutting debris exist in many workshops. Foreign particles easily penetrate bearings and accelerate wear of rolling elements. The market demands integrated cam follower bearings with high outer ring strength, excellent wear resistance, impact resistance and stable precision.
NMT Cam Follower Bearings are manufactured from high-toughness bearing steel. Thick-walled outer rings receive enhanced heat treatment to resist plastic deformation caused by contact compression. The outer circular surface of outer rings is precisely ground and polished to realize smooth rolling and reduce contact surface abrasion. High-precision rolling elements are assembled inside to achieve even load distribution, low vibration and guarantee positioning accuracy of moving mechanisms.
The integrated stud shaft allows direct threaded locking installation without extra bearing housings and simplifies mechanical structures greatly. Dust-proof sealing structures are optional to block dust and debris and protect rolling contact surfaces. Long-service grease lubrication is supported to lower maintenance frequency. Complete standard sizes support direct replacement of universal cam follower bearings and renovation of new and old automation equipment. Larger-size models are available for heavy-load conditions to raise overall load limit and withstand transient impact loads.
