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 LM/LM-AJ/LM-OP linear motion bearing,standard type/adjustable type/open type optional

Conducive To Environmental Protection

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