Project Description

Low maintenance slide bearings Splite Bushes Flange Type,Multilayer Sliding Bushing,ISO 3547,On this page you can find the complete product range of low maintenance bushings from

The boundary lubricated bearing is made of steel plate as the matrix, sintered spherical bronze powder in the middle, surface rolled modified POM, and contains oil storage pit.It is suitable for normal temperature, low speed and medium load places, replacing the traditional copper cover not only reduces the cost but also prolongs the service life.It can save the frequency of refueling and simplify the replacement procedure.


The dry sliding bearings bushings have been widely used in automotive chassis, forging machine tools, metallurgical mining machinery, engineering machinery, hydropower, steel rolling industry and other fields.

Assembling Instructions

The edges of the mounting hole and the shaft must be chamfered. It is recommended to use an arbour press. Please avoid damaging the sliding surface. The butt joint should not be in load direction.

Bushing Design

Bushing materials is filled ptfe modified polyformaldehyde plastics for the surface layer of three layer composite self-lubricating materials, it is a kind of benign boundary lubrication material, thus is especially with high load under the low speed of rotation, swing movement and often opening and closing under load and not easy to form hydrodynamic lubrication of bearings, thrust washers, slider, ball seat and other friction parts.Multilayer Sliding Bushing can make full use of trace lubricating grease, which can be used for long-term maintenance without refueling under boundary lubrication condition.Under the condition of completely without oil lubrication, the dry sliding friction bearings performance and allow the PV value is low, so often in the plastic surface of the rolling oil storage pit, fitting was coated with lithium base grease or silicon grease, etc.
