1 TECHNICAL SPECIFICATIONSFor a well understanding of this catalogue, we hereby explain the most important technical specifications which we will use frequently. For a slide bearing with an internal diameter d and a length L :

• Specific load = P (N/mm2)

If F is perpendicular charge (N):

P = F d . L

• Sliding speed = V (m/s)

Bush rotation: if n is the rotation speed (min-1)

V = d . π. n 60 . 103

Bush oscillation: if n is the oscillation frequency (min-1) and µ the angle of oscillation :

V = d . π . 2µ . n 60.103 360

• PV-factor = P.V ( N/mm². m/s)The PV factor is the specific load multiplied by the speed.It is the most important factor to size an application.

2 CALCULATION OF THE LIFESPANThe operating life for a slide bearing depends on the specific load, the sliding speed, the temperature and the material of the rod (surface roughness and hardness).On request, we can calculate the lifespan, which will be an approximate value.

3 PROTECTION OF THE ASSEMBLIESTo avoid any pollution of your bushing, we recommend the use of wipers 10SWP or 10SWPM on both sides (Fig. 956).

6 ASSEMBLY OF ROLLED BEARINGS (D > 50mm)For the assembly of slide bearings with a external diameter larger than 50 mm, we recommend the use of a mounting ring as shown in Fig. 957D.On request we can calculate the force FE.

5 ASSEMBLY OF ROLLED (D ≤ 50mm), MASSIVE AND COMPOSITE BEARINGSTo assemble rolled slide bearings with an external diameter up to 50 mm, please proceed as shown by Fig. 957C.The adapted diameter at size h gives us the possibility to press the bearing in the housing with a depth h.

4 DESIGN OF THE ASSEMBLIESTo avoid stress concentrations on the edges of the bearing, it is preferable to provide a small clearing or let the bearing protrude (Fig. 957A and Fig. 957B).

23BK-1 are tri-layer maintenance-free bushings with a base of low carbon steel, whereupon a porous bronze layer is sintered. After rolling process completed, PTFE is impregnated into the interstices of this bronze layer.23BK-1 self-lubricating bushings offer very good wear and low friction performance even in dry running conditions and have good physical and mechanical properties, also certain chemical properties.They are suitable for linear, rotating and oscillating movements.

23BK-1...F are tri-layer maintenance-free flanged bush-ings with a base of low carbon steel, whereupon a porous bronze layer is sintered. After rolling process completed, PTFE is impregnated into the interstices of this bronze layer.23BK-1...F self-lubricating flanged bushings offer very good wear and low friction performance even in dry run-ning conditions and have good physical and mechanical properties, also certain chemical properties.They are suitable for linear, rotating and oscillating movements.

23BK-3 bi-metallic bushings are formed from steel strips with alloy lining material in bronze CuPb10Sn10. In the bronze alloy sliding layer are circular lubrication pockets machined allowing long-term lubrification.23BK-3 are suitable for medium loads at mid-high speed rotation or oscillating movement.

23BK090 bronze wrapped bushings are entirely made of bronze CuSn8.They are fitted with diamond shaped lubrication indents on the bearing surface. The indents serve as lubricant reservoirs to rapidly build up a lubricating film at the start of movement, allowing to reduce the running friction, resulting in an excellent and prolonged operation.These bronze bearings have been developed for high-load applications at lower speeds and are especially suited for oscillating mouvements. They are perfect for polluted working conditions such as in the construction or agricultural industries.

23FT090 is deriving from 23BK090. The difference between the two is that the indentations are replaced by through holes.The difference between both is, that the indentions are substituted by through-holes. These holes allow a larger capacity to collect lubricant, which build up a lubrication film at the start of movement and reduce the friction. It is suitable for high load, lower speed application like construction, Transport, and agriculture machinery.These bronze bearings have been developed for high-load applications at lower speeds. They are perfect for polluted working conditions such as in the construction or agricultural industries.

23HST is a line of steel bushings that undergo case-hardening and tempering treatment with casehardening depth of 0.8-1 mm and Hardness HRC 58-62. The smoothness obtained by this treatement reduces the friction factor and consequently makes the bush more efficient.The use of these bushes, after an initial greasing cycle, enables a lubrication interval of up to 550 h. max. (the interval varies based on the working conditions).Each bush is traceable and identifiable thanks to the indelible marking on each piece, which identifies the lot.

23BK500-15N are composite bearings consisting of synthetic fabrics impregnated with thermosetting resins, evenly dispersed solid lubricants and other additives. 23BK500-15N bushings offer significant advantages over traditional metal bearings. All are dimensionally stable, have excellent wear resistance and outstanding low-friction characteristics, giving them unrivalled per-formance in dry running conditions or with boundary lubrication. With virtually no swell in seawater, they are ideal for marine and hydropower applications.

All information mentioned in this catalogue is based on the knowledge obtained through a long experience in the manufacturing and application of seals. However, unknown factors in the field of sealing can considerably change the conditions which may cause this information to be invalid.The pressure, temperature and speed values in this catalogue are maximum values which can never be used simultaneously. The maximum pressure allowed by the seal will depend on temperature, speed and gap dimension e.
