Metal plastic polymer
SF-1P oilless lubrication bearing (reciprocating type)
Product parameters
Substrate properties
Oil-free bearings (oil-free plain bearings) are used for plain
bearings. Oil-free lubricated bearings are designed for
self-lubricating, oil-free bearings, smooth operation, reliable,
and noise-free. Liquid lubrication conditions, separated from the
lubricant does not directly contact the sliding surface, you can
greatly reduce friction loss and surface wear, this film also has a
certain degree of impact absorption.
Our Products are widely used in printing machinery, food machinery,
mining machinery, fitness equipment, molds, hydraulic machinery,
hydraulic machinery, machine tools, hydraulic turbines, steam
turbines, injection molding machines, plastic molding machines,
metallurgical equipment, construction machinery, automobiles,
valves, pumps, lifts, power tools, textile machinery, rubber
machinery, etc.
Material organization
1. PTFE / fluororesin layer thickness 0.05 ~ 0.10mm, dry friction,
can be reworked to obtain a higher tolerance level.
2. The copper powder layer is 0.20~0.35mm, which has good
load-bearing capacity and wear resistance. Good thermal
conductivity can transfer the heat generated during the operation
of the bearing. The composite material can penetrate into the gap
of the copper powder ball to improve the bonding strength.
3. Low carbon steel provides good load bearing performance and heat
transfer.
4. The copper/tin plating layer is 0.002mm, which makes it have
better corrosion resistance.

typical application
Due to the thick PTFE lubricating layer, SF-1P oilless lubricating
bearings (reciprocating type) are mainly used in precision parts
such as automobile belt tensioners, pulleys, solenoid valves, air
conditioner compressors, and hydraulic pumps．
Oilless sliding bearing refers to a special bearing
The shaft portion of the bearing is called the shaft diameter
portion, called the bush and the shaft diameter go together. In
order to improve the friction bearing surface properties of the
friction material of the inner surface layer of the casting, it is
called a bearing lining.
The materials for the bearings and bearing linings are collectively
referred to as bearing materials. Bearing applications typically
load conditions, maintenance and lubrication or difficult operating
areas at low speeds and weights.
