NMT Cam Follower Bearings High Impact Resistant Wear-Resistant Precision Cam Follower Roller Bearings For Automatic Production Lines, Machine Tools And Conveying Equipment
Cam mechanisms inside automatic production lines and stamping equipment perform long-term reciprocating cyclic motion. The outer surfaces of rollers keep contacting and rubbing against guide rails and cams repeatedly. Ordinary roller bearings feature thin outer rings. Under cyclic impact loads, surface spalling and deformation wear easily occur, causing vibration and abnormal noise, reducing conveying positioning accuracy and disturbing the stability of the whole production line.
Plenty of metal scraps and dust exist in machine tool processing workshops. Simple unsealed rollers are vulnerable to impurity intrusion, resulting in rolling element jamming and mechanism seizure. Most cam transmission devices have limited installation space. Separated bearings with bearing housings require complicated assembly and occupy extra space, hindering compact equipment design. Ordinary commercial rollers have insufficient wear resistance and require frequent replacement, bringing heavy downtime losses. The market demands precision cam follower bearings featuring integrated installation, impact and wear resistance and reliable sealing.
NMT Cam Follower Bearings adopt high-purity bearing steel and integral forging. The stud delivers sufficient tensile strength for direct threaded locking, simplifying machine structure design. The profile of thickened outer rings is optimized through simulation to evenly distribute contact stress, avoid local stress concentration and greatly improve impact and wear resistance.
Needle rollers are processed via ultra-precision grinding with consistent dimensional accuracy for smooth rotation and reduced vibration caused by clearance. Open type and rubber sealed versions are optional for clean workshops and dusty processing sites. A complete specification range covers light, medium and heavy load conditions with excellent interchangeability. Sufficient internal space for grease filling maintains long-term lubrication and lowers maintenance frequency, ideal for continuously circulating automated mechanisms.
