SKF 51102 Single Direction Thrust Bearing – Grooved Race, ABEC 1

Description

Product Overview

The SKF 51102 is a single direction thrust ball bearing designed for demanding industrial environments. Constructed with a precision‑ground grooved race and an ABEC 1 rating, this bearing ensures minimal vibration and high rotational accuracy. The steel cage provides excellent separation of the balls, reducing wear and extending service life. With a 15 mm bore, 28 mm outer diameter, and a 9 mm width, the bearing fits a wide range of shafts and housings. Its static load capacity of 3150 lbf and dynamic capacity of 2100 lbf make it suitable for heavy‑duty applications where both radial and axial forces are present.

Usage

This thrust bearing excels in machinery that experiences axial loads, such as gearboxes, conveyors, pumps, and rotary tables. It is ideal for applications that require a single direction of thrust, providing reliable performance in high‑speed rotations up to 10,000 rpm. The bearing’s compact dimensions allow it to be integrated into tight spaces, while its robust construction ensures longevity even in harsh environments with temperature fluctuations and exposure to contaminants.

FAQ

What is the maximum operating speed for the SKF 51102 bearing?

The bearing is rated for speeds up to 10,000 rpm under standard lubrication conditions, making it suitable for most high‑speed industrial applications.

Can this bearing be used in both clockwise and counter‑clockwise rotations?

Yes, the SKF 51102 is a single direction thrust bearing, meaning it can accommodate axial loads in one direction while allowing rotation in either clockwise or counter‑clockwise direction.

What lubrication method is recommended for optimal performance?

SKF recommends using a high‑quality grease with a NLGI grade of 2. Apply a thin, even layer to the raceways and cage to ensure consistent lubrication and protect against contamination.

Is the bearing compatible with standard shaft sizes?

The 15 mm bore fits standard 15 mm shafts. For other shaft diameters, a suitable sleeve or adapter can be used to achieve a secure fit without compromising performance.

How does the ABEC 1 rating affect the bearing’s performance?

An ABEC 1 rating indicates a high level of dimensional precision, which translates to reduced run‑out, lower vibration, and smoother operation, especially important in precision equipment and high‑speed machinery.

Overall, the SKF 51102 single direction thrust bearing combines robust construction, precise engineering, and comprehensive support to deliver reliable performance across a broad spectrum of industrial applications.
