Key Features
- Premium Bearing Steel ConstructionThe outer shell and steel balls undergo dedicated heat treatment for high surface hardness and outstanding wear resistance. The material features a high melting point, stable mechanical performance and excellent impact resistance for continuous heavy-duty operation.
- Dual-Side Dust-Proof Sealing DesignDouble rubber sealing rings on both ends prevent foreign particles and pollutants from entering the ball circulation path. The sealing structure retains lubricant inside the bearing and reduces grease leakage, greatly improving durability in dusty workshop environments.
- Silent & Smooth OperationPrecision graded steel balls run inside the nylon cage with uniform clearance control. The rolling friction design minimizes running noise and heat generation, supporting stable reciprocating linear motion at continuous travel speeds.
- Complete Size Portfolio & Multiple VariantsThe LME3 series covers shaft diameters from 3 mm up to 60 mm. Three structure options are available: standard type, AJ clearance adjustable type and OP open type. Engineers can select or combine models according to load, precision and installation needs.
