Angular Contact Ball B. SKF 7216 BECBP
The 7216 BECBP angular contact ball bearing from SKF Wälzlager, with a contact angle of 40 degrees, can accommodate high unilateral axial loads within an 80x140x26 mm installation space.
The 7216 BECBP angular contact ball bearing from SKF Rolling Bearings is a single-row rolling bearing designed for combined loads with a significant axial component. The dimensions are 80 mm bore, 140 mm outside diameter and 26 mm width. Manufactured from standard rolling bearing steel (100Cr6), it is designed for oil- or grease-lubricated industrial applications. The integrated polyamide cage guides the rolling elements at operating temperatures ranging from –20 to +120 degrees Celsius.
What loads can the 7216 BECBP angular contact ball bearing withstand?
Single-row angular contact ball bearings of this design transmit forces via raceways set at an angle with a contact angle of 40 degrees. As a result, this design accommodates high axial forces in one direction as well as simultaneously acting radial forces. In industrial shaft mountings, the component guides rotating shafts with precision. To accommodate axial forces acting in both directions, fit a second bearing in an O or X arrangement; this variant is designed by the manufacturer to ensure minimal axial play.
What is important to consider regarding the polyamide cage and tolerances?
The cage material and tolerance classes play a decisive role in bearing design. The lightweight polyamide cage reduces friction and inertia and is suitable for temperatures up to +120 degrees. The tolerance class combines dimensional accuracy to P6 with finer running accuracy to P5, which promotes uniform concentricity. As the component is designed as an open type without sealing washers, the bearing location requires an external housing seal as well as a continuous supply of lubricant to protect against solid particles and moisture.
What are the technical features of the 7216 BECBP angular contact ball bearing?
This single-row roller bearing has a contact angle of 40 degrees, which accommodates high axial forces in one direction. Manufactured from standard roller bearing steel 100Cr6, this version features a polyamide cage and standard radial clearance. With dimensions of 80 × 140 × 26 mm, the component achieves dimensional accuracy to P6 and running accuracy to P5.
What is the purpose of the 40-degree pressure angle?
The contact angle defines the line of action of the force transmission between the balls and the raceways. An angle of 40 degrees allows for high axial load capacity whilst also withstanding radial loads. The bearing is suitable for dominant axial forces in one direction and requires a matching mating bearing for loads acting in both directions.
How can the 7216 BECBP angular contact ball bearing be fitted as a pair?
This design is intended for universal installation in sets. When fitted in pairs in an O or X configuration, a defined, small amount of axial clearance is created as a result of the system design. This facilitates precise fitting into housings and onto shafts, as you do not need to adjust the axial clearance using additional shims.
What are the characteristics of the integrated polyamide cage?
A polyamide cage is characterised by its low weight and elastic material properties. It dampens mechanical vibrations and ensures smooth running of the rolling elements. The permissible temperature range is from –20 to +120 degrees Celsius, which must be taken into account in thermally demanding operating conditions.
Why does the open bearing require external sealing?
The component is supplied ex-works without either face seals or contact seals. To prevent lubricant loss and to prevent the ingress of dirt or moisture, the surrounding structure must be fitted with external shaft seals or labyrinth seals. A suitable initial greasing or oil lubrication is also required prior to commissioning.
What do the tolerance classes P6 and P5 mean for this bearing?
The specifications describe the permissible manufacturing tolerances of the rolling bearing. Dimensional accuracy to P6 defines tighter tolerance ranges for the bore, outer diameter and bearing width. Running accuracy to P5 reduces the radial and axial runout errors of the rings, which minimises vibrations under dynamic loading.
