7008B Angular Contact Bearing 40x68x15 Ball Bearings VXB Brand
Price:


Product Feature
- Single-row angular contact ball bearing, supporting moderate one-directional thrust loads, and combined loads where thrust load is predominant
- Ball contact angle of 40 degrees relative to the inner and outer raceways increases thrust load capacity
- Open configuration for lubrication applied in place
- Pressed steel cage evenly spaces balls for reduced friction, vibration, and noise
- Normal axial internal clearance for applications where thermal expansion is not a factor
Product Description
The VXB 7008B single-row angular contact ball bearing is an open bearing and has a 40-degree contact angle, pressed steel cage, and normal clearance rating. It supports moderate one-directional thrust loads, and combined radial and thrust loads where the thrust load is predominant. This bearing is made of low-alloy, through-hardened carbon chromium steel for durability and resistance to deformity under heavy loads. The 40-degree contact angle of the balls in relation to the raceways gives the bearing a greater capacity for supporting thrust loads over bearings with a lower contact angle. Its open design facilitates lubricating the bearing in place and dissipating heat. This bearing has a pressed steel cage to prevent the balls from coming into contact with each other during use, reducing friction, vibration, and noise. The bearing has a normal axial internal clearance designation, making it suitable for applications where the load and speeds do not result in thermal expansion. This clearance provides latitude for self-realignment and compensates for static and dynamic alignment errors. This angular contact ball bearing is for use in commercial and industrial applications including pumps and compressors, automotive drives, gearboxes, and printing machines, among others.
Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All rolling bearings are open, shielded, or sealed. Sealed bearings are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use. The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.
7008B Angular Contact Bearing 40x68x15 Ball Bearings VXB Brand Review
Tried this low cost bearing for the lower spindle on an old Index mill I have.Can't beat the price! I dont have any time or load on it, but its quiet and smooth like new bearings should be.
I was thinking of buying 2 more for spares, but the original bearings lasted 50 years, lol.
