Angular Contact Ball B. FAG 7312 -B-XL-TVP
The FAG 7312 -B-XL-TVP single-row angular contact ball bearing, measuring 60x130x31 mm, can accommodate radial and one-way axial loads.
The FAG 7312 -B-XL-TVP from FAG is a single-row rolling bearing made from standard bearing steel (100Cr6) with a bore of 60 mm, an outer diameter of 130 mm and a width of 31 mm. Due to the asymmetrical design of the raceways, this design is specifically suited to combined forces. It is manufactured to tolerance class P0/PN or ABEC 1. The open component has a standard radial clearance and is designed for a temperature range of -20 to +120 degrees.
What is the 7312 -B-XL-TVP angular contact ball bearing with a 40-degree contact angle suitable for?
Single-row angular contact ball bearings of this design transmit forces at an angle to the radial plane. The 40-degree contact angle enables the bearing to accommodate not only radial forces but also significant axial forces in one direction. Typical applications include shaft mountings subject to combined loads. Users frequently fit these bearings in pairs to absorb axial forces on both sides.
What are the distinctive features of the TVP polyamide cage and the open design?
The TVP version features a lightweight polyamide cage which guides the rolling elements and reduces the moment of inertia. As this is an open bearing without an integrated seal, designers can tailor the lubrication individually using external lubrication systems or housing seals. During installation, the direction of the axial load must be taken into account, as the bearing’s design means it can only absorb axial forces in one direction.
What are the dimensions of the 7312 -B-XL-TVP angular contact ball bearing?
With a cylindrical bore of 60 mm, an outside diameter of 130 mm and a width of 31 mm, the bearing complies with standardised dimensions. The outer ring is designed without a flange or groove. These dimensions allow for a precise fit when installed in housings and on shafts of the corresponding nominal size.
What is the significance of the 40-degree pressure angle?
The contact angle determines the direction in which the rolling elements transfer the load from the inner to the outer ring raceways. A contact angle of 40 degrees, indicated by the suffix ‘B’, enables a high axial load capacity. The force is transmitted at an angle to the radial plane, designed to accommodate unilateral axial loads.
What does the suffix ‘TVP’ mean in relation to FAG rolling bearings?
The suffix ‘TVP’ denotes a polyamide cage that guides the rolling elements within the bearing. This material is characterised by its low weight and contributes to quiet operation. The permissible temperature range for this bearing with a polyamide cage is between -20 and +120 degrees.
How is an open angular contact ball bearing lubricated and sealed?
Open angular contact ball bearings do not have integrated sealing washers and are suitable for external lubrication systems such as oil circulation or individual grease filling. The surrounding structure provides protection against the ingress of contaminants. Users select housing seals, shaft seals or labyrinth seals to suit the respective environmental conditions.
In which tolerance class is this bearing manufactured?
The designations P0/PN and ABEC 1 denote the standard tolerance class for dimensional, geometric and running accuracy in mechanical engineering. This specification covers common industrial applications and defines the fit dimensions for bearing seats on cylindrical shafts and in housing bores.
Why does a single-row angular contact ball bearing usually require a mating bearing?
By their very design, single-row angular contact ball bearings can only accommodate axial loads in one direction. Under purely radial loading, an internal axial force is generated within the bearing. Designs therefore usually require a second bearing or a set of bearings arranged in a mirror image in an O or X configuration in order to achieve a backlash-free shaft guidance system.
