Double Row Angular Contact Ball Bearing

View Details

Angular contact ball bearings feature a unique design where the balls make contact with the raceway at a specific angle. This angular contact allows the bearing to support higher axial loads while maintaining smooth rotational movement and operational stability.

These bearings are manufactured using high-quality materials, corrosion-resistant coatings, durable cages, and advanced lubrication systems to ensure long service life and dependable performance in demanding industrial environments.

Types of Angular Contact Ball Bearings

Single Row Angular Contact Ball Bearings:- Designed with a single row of balls, these bearings support combined loads and are commonly used in high-speed and precision applications.
Double Row Angular Contact Ball Bearings:- These bearings feature two rows of balls, offering higher load capacity and improved rigidity for demanding industrial applications.

Angular Contact Ball Bearing Supplier in India — Aarya Sales

Angular contact ball bearings (ACBB) have raceways offset so the load line is at an angle to the bearing axis, allowing them to carry combined radial and unidirectional axial loads simultaneously. Contact angle options: 15°, 25°, 30°, 40° (higher angle = more axial capacity). Used in matched pairs (DB/DF/DT) or sets of four for spindle applications. Aarya Sales supplies ACBB in bore sizes 10 mm to 320 mm.

Applications: machine tool spindles, pumps, high-speed gearboxes, precision instruments, aviation, and semiconductor equipment. Single-row 70XX (15°) and 72XX (25°/30°) series; double-row 52XX and 32XX series; four-point contact 60XX series. Precision grades: P4A (ABEC 7), P4 (ABEC 7), P5 (ABEC 5), P2 (ABEC 9) for spindle applications.

Frequently Asked Questions

An angular contact ball bearing has a designed contact angle between the ball-raceway contact line and the radial plane (perpendicular to the shaft axis). Common angles: 15° (high speed, light axial), 25° and 30° (medium combined loads), 40° (high axial load). Higher contact angle = greater axial capacity but lower speed limit.

A single-row ACBB supports axial load in only one direction. Paired mounting (face-to-face DF, back-to-back DB, or tandem DT) supports bidirectional or combined loads. Preloaded matched pairs (universally matchable) are used in machine tool spindles for maximum stiffness and runout accuracy.

DB (back-to-back/O-arrangement): wide effective load span, greater tilting stiffness, preferred for cantilever loads and bending moments. DF (face-to-face/X-arrangement): narrower load span, more tolerant of misalignment, preferred for applications with thermal expansion.

Single-row: 70XX (C/AC/B, 15°/25°/40°) and 72XX (C/AC) series from 10 mm to 320 mm. Double-row: 52XX series (25° contact). Four-point contact: 60XX series. Universal match-ground pairs (suffix UA) for spindle mounting. Precision classes P0 to P2.

Machine tool spindles (CNC milling, turning, grinding), high-speed centrifugal pumps, turbochargers, small gearboxes, screw compressor rotors, precision instruments, aerospace gyroscopes, and dental/surgical equipment where high speed and precision are simultaneously required.

Reference speed depends on size and contact angle. Small 70-series bearings (15° contact, grease) can run at 50,000–100,000 RPM. Speed factor (n × dm) up to 1.5–2.0 million for oil-air lubricated high-speed spindle bearings.
