Product Description

Dryslide Bushings Standard Flange Size Teflon PTFE Dry Sliding Bearing Bushes In Air Compressor

The Dryslide Bushings trademark identifies a whole range of self-lubricated dry sliding bushings and bearings. The bushings have a composite structure consisting of a carbon steel backing, an intermediate layer of sintered bronze and a PTFE based sliding lining.  The Dryslide Bushings have a composite structure consisting of a carbon steel backing onto which a porous layer of bronze is sintered and then impregnated with a co-acetal plastic.

Dry Sliding Bearing

Tuleje suche LBM SANKYOBushes Steel Backed Bronze Dimensions,LBM dry bushing ( bushing) material: teflon steel backed (PTFE) bearing with improved self-lubrication due to the addition of low friction coefficient polytetrafluoroethylene (PTFE), LBM bearing has wear resistance.



lead-free bearing, no lubrication can be used;

Excellent wear resistance;

Long service life;Suitable for sliding;

Quiet operation during the journey;

A large number of available dimensions.



do not grind the inside or outside of the sleeve to adjust its size;Move the sleeve connection away from the maximum load point as far as possible;To install the sleeve, slide it vertically into the housing;No special locks required;Prelubrication can extend product life.

Standard Flange Size Teflon PTFE Dry Sliding Bearing Bushes In Air Compressor


The basic characteristics of

The product is made of high quality low carbon steel with a sintered spherical bronze layer and a mixture of polytetrafluoroethylene (PTFE) rolled on the surface.


It has good self-lubrication, wear resistance, low friction coefficient, good performance, low noise and other properties, products are widely used in a variety of mechanical sliding parts.

PTFE/Pb mixture 0.01~0.03mm, a wear-resistant material that forms a transfer film to protect the shaft during operation.
Copper powder layer 0.2~0.35mm improves the bonding strength of PTFE and steel plate, with good bearing capacity and wear resistance.At the same time copper is a good thermal material, can quickly transfer the heat generated in the process of bearing operation.

Low carbon steel, improve bearing capacity and heat transfer.

Copper/tin plating of about 0.002mm, so that the bearing has good corrosion resistance.

To form
Straight sleeve, flanging sleeve, WC thrust gasket, slide plate and other non-standard parts, etc.



·No oil lubrication or less oil lubrication, suitable for oil can not be refueling or more difficult to refueling occasions, can be used without maintenance or less maintenance;

·Good wear resistance, small friction coefficient, long service life;

·Can be used in the range of -190℃ ~ +280℃;

·Good running performance, low noise, no pollution;

·Thin-walled structure, light weight, can reduce the mechanical volume;

·During operation, it can form transfer film, which can protect the grinding shaft without biting the shaft.

·The hardness of the grinding shaft is low, and the shaft can be used without tempering treatment, thus reducing the processing difficulty of related parts;

·No water absorption, oil absorption, small thermal expansion coefficient, good heat dissipation, size stability;

·The back of the steel can be plated with a variety of metals, so it can be used in corrosive media, no rust;


Currently has been widely applied to various mechanical sliding parts, such as automatic mechanical equipment (scale, swing, slide, bending, cyclotron, turning parts) hydraulic cylinder guide sleeve, gear pump pu, textile machinery, vending machines, plastic molding machine, die-casting machine, rubber machinery, tobacco machines, fitness equipment, office machinery, hydraulic truck, automobile, motorcycle, agriculture and forestry.
