Angular Contact Ball B. FAG 3214 -B-TVH-C3
The FAG 3214 -B-TVH-C3 angular contact ball bearing, with a 70 mm bore, can accommodate high radial loads and axial forces on both sides whilst maintaining a compact width.
The double-row angular contact ball bearing 3214 -B-TVH-C3 combines the load-carrying capacity of two individual bearings arranged opposite each other in a fixed assembly. Manufactured from through-hardened standard roller bearing steel 100Cr6, the component precisely guides shafts with a 70 mm diameter within the assembly. Thanks to its contact angle of 40 degrees, this roller bearing effectively supports axial forces in both directions. The design complies with tolerance class P0 (ABEC 1) and is suitable for demanding industrial applications.
In which installation scenarios does the double-row angular contact ball bearing 3214 -B-TVH-C3 prove its worth?
This double-row roller bearing is suitable for bearing arrangements where combined loads consisting of radial forces and axial forces on both sides occur. Typical applications include industrial bearing arrangements with combined loads, shaft guides and compact drive units. Design engineers appreciate this design as it saves axial installation space compared with two separate individual bearings. The rigid guidance ensures precise centring of the rotating machine components.
What advantages do the polyamide cage and C3 clearance offer in this FAG design?
The suffixes indicate material- and function-specific properties of the bearing assembly. The polyamide cage (TVH) ensures quiet running, reduces the weight and dampens vibrations during operation between –20 and +120 degrees. The C3 designation indicates increased radial bearing clearance. This additional clearance compensates for operational thermal expansion between the inner and outer rings and counteracts premature tightening of the system.
What are the dimensions of the 3214 -B-TVH-C3 angular contact ball bearing?
With a bore diameter of 70 mm, an outside diameter of 125 mm and a width of 39.7 mm, the bearing complies with the standardised main dimensions for double-row series. The outer ring is cylindrical in design and has neither a flange nor a retaining groove. These dimensions allow for direct integration into standardised bearing housings.
What does the suffix ‘TVH’ mean in the context of FAG?
At FAG, the abbreviation TVH refers to a solid polyamide cage which precisely guides the rolling elements and maintains the correct spacing between them. The material operates quietly, reduces friction losses and allows for use at operating temperatures ranging from –20 to +120 degrees Celsius. For continuous operating temperatures above this range, alternative metal cages are required.
Why is the increased clearance C3 necessary?
C3 indicates an increased radial bearing clearance compared with the standard value. Designers choose this variant when there are temperature differences between the shaft and the housing, or when tight fits reduce the operating clearance after press-fitting. It prevents radial stress on the ball sets during operation.
Is the 3214 -B-TVH-C3 angular contact ball bearing sealed?
This is an open-type bearing design without integrated cover plates or sealing washers. The design requires the surrounding assembly to be protected against dirt and moisture by means of external sealing elements. Furthermore, the open design requires a direct supply of grease or lubricating oil via the housing.
What forces does the 40-degree contact angle exert?
The 40-degree contact angle distributes the forces acting on the bearing diagonally to the radial plane via the two rows of balls. As a result, the bearing can accommodate high radial loads whilst simultaneously transmitting considerable axial forces in both thrust directions, without the need to fit a second individual bearing.
What material is the bearing made of?
Bearing rings and rolling elements are made from conventional standard rolling-bearing steel in accordance with material standard 100Cr6. This case-hardened steel offers high wear resistance, high compressive strength and dimensional stability under continuous load. In corrosive environments without lubricant protection, the material must be protected from moisture using suitable lubricants.
