Cam followers

Cam followers

Cam followers have a reinforced outer ring that serves as a running area and preferably has a spherical design so that no edge stresses arise under high loads. Unlike yoke type track rollers, cam followers have a threaded end for simple installation. For simplified installation, there are designs with a slot for a screwdriver or a hexagon socket. Designs with an eccentric on the shaft allow the outer ring race to be adjusted in relation to the raceway.

Technical information

PP/2RS: integrated contact seals..

Note: The NUKR series has a labyrinth seal due to a seal washer sheet.

Cam followers can be relubricated in various ways. There are different designs depending on the manufacturer. Designs with a hexagon socket (suffix SK or 2SK) usually have an integrated front lubrication nipple or an additional one at the rear. In addition to this, cam followers can be relubricated in the shaft by means of a central lubrication system via a lubrication groove with a lubrication hole.

Caution: Designs with an eccentric ring cover the lubrication groove with a lubrication hole in the shaft and can as a result only be relubricated from the front or rear.

Note:
As standard, ABEG® needle-roller bearings are supplied ungreased and only preserved. However, some other manufacturers provide them with a lithium complex soap grease ex works. Please ask your dealer or specify the design you want when ordering.

Designs with a V in their name are full complement designs. Full complement designs have a significantly higher load rating. However, this reduces the maximum speed.

Identifying and repairing rolling bearing damage
Identifying and repairing rolling bearing damage.

Rolling bearing damage can have a wide variety of causes and is not necessarily caused by a faulty original product. However, most companies are unable to carry out a detailed damage analysis – good thing Findling Wälzlager’s experts can provide further assistance here: Damage analysis is part of the service portfolio. Findling Wälzlager acts as an independent partner that looks into the causes of the ball bearing defects and helps solve problems.

Inner rings ground without twisting
Inner rings ground without twisting for optimum raceways

The use of inner rings ground without twisting, for example in conjunction with radial shaft seals, comes with a series of advantages: Among other things, this makes it possible to prevent lubricants from leaking and increases the service life of the sealing lips. Findling now also offers these components in two performance classes. A high degree of automation during production also allows large-scale production to benefit from attractive conditions and a maximum level of efficiency as well…
