AI Overview
The 7040AC is a high-precision, single-row angular contact ball bearing (200mm bore
310mm OD
51mm width) with a 25° contact angle (AC), optimized for high axial loads in one direction and high-speed, high-rigidity applications, commonly used in machine tool spindles. With a "25°" angle, it offers a balance of high axial capacity and moderate speed, often paired for combined loads.

People also ask
Are angular contact bearings better?
Angular contact bearings have a much higher speed rating than radial bearings because of the nonstop contact of the balls to both rings.

Which is better, RS or ZZ bearing?
If moderate protection from debris is needed without frequent maintenance: Opt for ZZ bearings. Their metal shields offer protection while still allowing for smooth, efficient operation. If your application requires maximum protection from dust, moisture, or other contaminants: Go for 2RS bearings.Dec 19, 2024

Can angular contact bearing handle radial and heavy axial thrust loads?
Angular contact ball bearings can support radial loads and axial loads in one direction. The line along the points where the balls contact the rings is inclined relative to the radial direction of the bearing. Due to this contact angle (α), an axial force is generated when a radial load is applied.

Do angular contact bearings need preload?
First, it's important to know that a preload is required for angular contact bearings. This is because of the bearing design; it needs constant contact to happen between the balls and raceway.
