Our range of Self-Lube® housings offers a wide choice of cast-iron or pressed steel bodies, equipped with the entire Self-Lube® bearing range with a spherical external diameter.
The main types of body are:
- Plummer block housing
- Flanged housings
- Take-up housings
- Cartridges and connecting rod ends
The choice of housing is closely linked to its use characteristics but the aesthetic appearance of the machine is often an equally decisive element. Our Self-Lube® housings have been designed, taking both elements into account.
The bodies are made of high-quality cast iron, as per BS1452; all non-machined surfaces are painted with an enamel electrostatic paint that dries in the air.
The metal bodies are made of soft steel as per BS1449 and are galvanised.
 |
Self-Lube® protectors Our protectors are designed to protect the operator from the danger represented by the rotating shaft ends and also to avoid deposits forming on the outer surfaces of the bearing. Protectors are made of good quality soft steel, covered with enamel paint, making them robust, attractive and durable. They are easy to assemble and can be removed without damage as many times as necessary. The two protector claws slot into the groove of standard bearings. This reliable fastening device allows for mounting without any additional fastener required. |
 |
Locking screw This locking system consists of two socket head locking screws positioned in the part extending beyond the inner ring. For normal loads and moderate speeds, the bearing is simply put in position and the screw tightened to the recommended torque. As an additional security measure, the shaft can be counterbored to receive the tip of the screw. |
 |
Eccentric clamp collar. A machined eccentric on the extension of the bearing inner ring fits into a similar steel clamp collar eccentric. It is locked in position by turning the collar in the shaft rotation direction until the cam effect locks the collar onto the shaft. The socket head screw maintains the assembly in this position. |
 |
Tapered adaptor sleeve This locking system consists of a tapered sleeve, bolt and a lockwasher and is recommended when concentric tightening on the shaft is necessary. When the bearing is mounted on the shaft, care must be taken to ensure the bolt is not too tight to avoid eliminating internal clearance and causing premature wear of the bearing. The purpose of the lockwasher is to prevent the bolt from becoming loose. |
Mounting precaution
It is essential to fix the housing in its final position on the machine frame and immobilise it in this position in relation to the rotating part before the inner bearing ring is tightened on the shaft.
Remove the socket head screws from the bore before inserting the shaft, which should be clean and chamfered.
Be careful not to strike the inner ring or body with a hammer and only apply mounting force on the inner ring. Once mounted, the bearing should rotate freely and effortlessly.
Cast iron housings should be arranged so that they operate in compression and not tension. Moreover, they should not be used in the event of reversible or pulse force.
In the event of considerable distance between housings, temperature variations may lead to dilatation phenomena that should be carefully studied.
Particularity of tapered bore mounts.
1 - Fix the housing onto the machine frame and ensure there are no traces of grease or oil on the shaft or in the tapered sleeve bore
2 - Position the shaft and hand-tighten the bolt
If the sleeve turns on the shaft, tap the tapered sleeve slightly to slide it into the bearing bore to ensure correct grip.
3 - Finish tightening the bolt by striking it with a punch and light hammer.
4 - Check that the shaft rotates freely to ensure internal clearance has not been eliminated and there are no constraints.
5 - Finally, lock the bolt with one of the lockwasher teeth.
6 - After 100 hours of service, bolt tightness should be checked.
