Angular Contact Ball Bearings

Angular Contact Ball Bearings – High Precision for Demanding Applications

At Simmering.pl, we offer a comprehensive range of angular contact ball bearings, engineered for precision, high-speed, and heavy-load applications. These bearings are designed to support combined loads, including both axial and radial forces, ensuring superior performance in critical industrial machinery, automotive systems, and high-speed spindles. Available in various configurations, including single-row, double-row, and four-point contact, our angular contact ball bearings meet the most demanding operational requirements.

Single-Row Angular Contact Ball Bearings

Single-row angular contact ball bearings are non-separable and feature a directionally oriented inner raceway. This design allows them to withstand high unidirectional axial loads. These bearings are available in multiple series, including 718.., 719.., 70.., 72.., and 73.., making them versatile for a variety of applications.

Key Features:

High axial load capacity in one direction
Optimized for high-speed applications
Non-separable construction ensures durability and reliability
Different cage designs for internal stability

Double-Row Angular Contact Ball Bearings

Double-row angular contact ball bearings function similarly to two back-to-back single-row bearings. They are designed to support axial loads in both directions and offer higher radial load capacity compared to single-row variants. These bearings are ideal for applications that demand enhanced durability and stability under combined loads.

Key Features:

Higher radial and axial load capacity in both directions
Excellent for applications requiring increased rigidity
Efficient space-saving design with two rows of balls
Available with different contact angles: 32°, 35°, and 45°

Single-Row, Double-Direction Angular Contact Ball Bearings (QJ Series)

These four-point contact bearings feature split inner or outer rings, enabling them to support axial loads in both directions. The QJ series is widely used in applications where space is limited but there is a need to accommodate high thrust loads in both directions, such as machine tool spindles or robotic arms.

Key Features:

Four-point contact design for axial loads in both directions
Compact and space-efficient
Ideal for high-speed applications
Available in standard contact angles of 23° and 35°

Bearing Types Available:

Single-Row Angular Contact Ball Bearings – standard and high-speed variants
Double-Row Angular Contact Ball Bearings – for increased load capacity
Single-Row, Double-Direction Angular Contact Bearings – four-point contact (QJ Series)
Matched Pairs of Angular Contact Ball Bearings – for tailored load distribution
