LMFM…L/LMKM…L/LMHM…L double-wide-middle flanged linear motion bearing

The Double-wide-middle flanged linear motion bearing is a precision-engineered component comprising an outer cylindrical housing, an inner spherical raceway surface, precision-ground steel balls, and a high-performance retainer designed to maintain optimal ball spacing. This configuration enables it to effectively withstand substantial radial loads while simultaneously accommodating moderate axial forces in both directions.

Key operational advantages include ultra-smooth linear motion achieved through precise ball circulation, minimal friction coefficients enabling high-speed operation up to [specific speed range if available], and exceptional stability even under fluctuating loads. The bearing's robust design incorporates corrosion-resistant materials and advanced sealing options, making it suitable for demanding environments including precision mold processing applications requiring sub-micron accuracy, high-vibration measuring instrument systems, and optical equipment demanding vibration-free linear guidance. Its flanged middle section provides enhanced mounting stability while maintaining compact overall dimensions for space-constrained installations.

Why Choose Oilless Bearings

Reduce Manufacturing costs

There is no need for oil supply device, oil injection hole or oil groove processing, which can greatly save manufacturing costs.

Reduce Operating Costs

It greatly reduces the usage of lubricating oil, reduces equipment maintenance, and avoids hidden dangers caused by insufficient oil supply, effectively reducing operating costs.

Shorten Design Time

The oil-free design simplifies the product structure and effectively saves design time. We are professional ODM Suppliers of LMFM…L/LMKM…L/LMHM…L double-wide-middle flanged linear motion bearing

Conducive To Environmental Protection

No waste oil recycling is required, which is also beneficial to environmental protection.
