1,Inside diameter of the bushing

Generally, the inside diameter of the bushing depends on the diameter of its mating axis.

2,Length of the bushing

The length of the bushing depends on the size of the pressure-shouldering surface. The longer the bushing, the less pressure at the surface, for the longer
bushing, the load on the bushing is relatively lessened. But simultaneously, it may result in deviation contact or lower cooling efficiency and thus shorten the
service life of the bushing. On the contrary, if the length of the bushing is too short, lubricating grease may quickly flow out of the bushing. Therefore, it hardly
forms a grease film and capability of the bushing is accordingly debased.

A comparison of L/d's effect on the bushings, especially oil lubricating bushings

Short bushing ( d>L)	Comparison items	Long bushing ( d<L)
Small	Force on the oil film	Great
Strong	Cooling ability	Weak
Can not be too high	Surface pressure	Can be high
High	Safety against beating deviation	Low
Weak	Bushing rigidity	Strong
Week	Shock absorbing ability	Strong
Small	Space	Large

3,Bushing thickness

The main advantage of standard composite self-lubricating bushings rest with their thin wall thickness. Standard thickness can be 0.5mm2, 0.75mm2,1.0mm2,
1.5mm2, 2.0mm2, 2.5mm2.

In thickness design of the non-standard gliding bushing, the designer could consult the following proportion of SB and D.

A) For thin wall thickness gliding metallic bushing, proportion between SB and D equals to 0.03 ~ 0.06.

B) For thin wall thickness gliding metallic bushing, proportion between SB and D equals to 0.08 ~ 0.12

C) For plastic gliding bushing, proportion between SB and D equals to 0.1 ~ 0.12

4,Bushing Chamfer

In order to make fixing easier and avoid deviation load, the bushing must be inner and outer chamfered in the direction of its length. Dimension of the
chamfer are showing in the following form.

Wall thickness	Out Chamfer Dimension	Inner Chamfer Dimension
<0.5	Burr polished	Burr polished
0.75	0.5 ± 0.3 x 20°	0.3+0.2 x 45°
1.0	0.6 ± 0.3 x 20°	0.3+0.2 x 45°
1.5	0.6 ± 0.3 x 20°	0.4+0.2 x 45°
2.0	1.2 ±0.3x20°	0.6+0.2 x 45°
2.5	1.8 ±0.3x20°	0.6+0.2 x 45°

Features of oil-free lubrication bearing series

1, no oil lubrication or less oil lubrication, can not be used for refueling or difficult to refuel the place, can be used in the maintenance or less maintenance.
2, wear resistance, friction coefficient, long service life.
3, there is the right amount of elastic-plastic, can stress distribution in a wide contact surface, improve the bearing capacity.
4, static and dynamic friction coefficient is similar to the crawl at low speed to eliminate, so as to ensure the accuracy of mechanical work.
5, can reduce mechanical vibration, reduce noise, prevent pollution, improve working conditions.
6, in the course of operation, can form a transfer film, play a role in protecting the grinding shaft, no bite axis phenomenon.
7, for the grinding shaft hardness requirements, are low, not quenched and tempered shaft can be used, thereby reducing the processing of the relevant parts difficult.

Characteristics

VSB-10 Self-Lubricating Multilayer Composite Bushing

Bushing material suitable for lubricated applications
self-lubricating bushings offer very good wear and low friction performance over a wide range of loads, speeds and temperatures in dry running conditions
Anti-friction bearing suitable for linear, oscillating and rotating movements
Material is designed to operate without supplemental lubrication and will perform excellently when lubrication is present. Low friction, low wear rate, good sliding characteristics, and very low absorption are a few of the features of this material. VSB-10 bushings will support the rotary, linear, and oscillating motion.

Structure

1. PTFE/Fibre mixture thickness 0.01~0.03mm. It is the contact surface for the rotating shaft. Minute parties of the PTFE layer and the sintered bronze material combine to create a solid lubricant film, which coats the shaft.

2. Sintered bronze powder thickness 0.20*0.35mm, A special composition of powdered copper is thermally fused to the steel backing. This contact layer acts as an anchor for the PTFE layer and conducts the thermal build-up away from the bearing surfaces.

3. Low-carbon steel backing. Setting the foundation of the bushings, the steel back provides exceptional stability, load carrying and heat dissipation characteristics.
