Odd size or no part number? What to send us to find your bearing

A good share of our work is finding bearings that are not on the shelf: sizes from imported machines, part numbers that were discontinued years ago, and bearings whose markings have worn away. With the right details we can usually identify one quickly. Here is what helps.

1. Three measurements

Using a vernier caliper, measure in millimetres:

• d: the bore (inside diameter)
• D: the outside diameter
• B: the width

Measure a clean, unworn surface and take two or three readings. If the bearing is imperial (inch) size, still send millimetres and we will convert. Sizes like 19.05 mm or 22.225 mm are a clue that it is an inch bearing.

2. Every marking you can see

Look on both faces of the rings, and on the shield or seal. Note the brand, the number, any letters before or after it, and the country of manufacture. Even part of a number helps. A clear photo is often better than copying it out.

3. Photos

Send three photos on WhatsApp, or use the quote form: the front face, the side (to show the width and any groove) and the markings close up. Put a ruler or coin next to it for scale.

4. Where it is used

• The machine it came from (make and model, if you have them)
• Rough speed (rpm) and whether it runs hot
• Whether the load is sideways (radial), end-on (axial) or both
• Whether the area is wet, dusty or has chemicals

This tells us whether you need a seal or a shield, a special clearance, stainless steel, or a high-temperature grease.

5. Quantity and urgency

Is this one bearing for a breakdown today, or fifty for a maintenance stock? Tell us. For urgent jobs we prioritise the order and arrange express delivery.

Or just bring it in

If you are in Mumbai, bring the old bearing to our counter in Kalbadevi. Holding it in the hand is still the quickest way to identify it, and we have been doing that since 1974.
