How to Assemble Universal Matched Angular Contact Bearings

2025-04-24
Latest company news about How to Assemble Universal Matched Angular Contact Bearings

 

1. Key Assembly Steps

Step 1: Align Markings

  • Check the high-point markings on the bearing’s inner and outer rings (pre-marked by the manufacturer).
  • Align these markings axially to ensure even load distribution.

Step 2: Choose Installation Method

  • Press Fit: Apply force only to the ring with an interference fit (inner or outer). Use a hydraulic press or sleeve.
  • Heat Fit: Heat bearings to 80–100°C (oil bath or induction heater) for easy mounting.

Step 3: Adjust Position

  • Rotate the bearings to align the inner ring’s high point with the shaft’s high point, minimizing eccentricity errors.

Step 4: Apply Preload

  • Use spacers or hydraulic nuts to set the correct preload (2–8 µm axial play).
  • Test: Rotate manually—smooth movement, no sticking or noise.

2. Critical Assembly Tips

A. Mounting Configuration

  • Back-to-Back (DB): Best for high tilting resistance (e.g., machine tool spindles).
  • Face-to-Face (DF): Ideal for high axial loads (e.g., short shafts).
  • Never mix bearings: Use the same brand/batch to avoid size mismatches.

B. Cleanliness & Precision

  • Work in a dust-free area. Wipe shafts and housings with lint-free cloths.
  • Recommended tolerances:

    Shaft: j5/k5 (interference fit).

    Housing: H6/J6 (slight clearance/interference).

C. Preload Control

  • Measure preload torque: ≤0.3 Nm.
  • For high-speed use (>5,000 RPM), reduce preload by 20–30% to offset heat expansion.

3. Common Issues & Fixes

Issue

Cause

Solution

Bearing jamming

Over-press fit or debris

Re-machine shaft or clean parts

Noise/Vibration

Misaligned markings

Reassemble with correct alignment

Overheating

Excessive preload

Reduce preload or use high-speed grease

4. Why Choose Beining Technology?

  • Precision Bearings: ABEC 5 to ABEC 9 grades for accuracy ≤3 µm.
  • Durable Materials: Nitrided steel or ceramic options for long life.
  • Expert Support: Free technical guides and 24/7 customer service.
