NACHI 32005JS Tapered Roller Bearing 25 x 47 x 15 mm

The NACHI 32005JS is a tapered roller bearing in the 32000 series with a 25 mm bore (the last two digits of 32005 give the bore: 5 x 5 = 25 mm). The AIMS listing gives its size as 25 x 47 x 15 mm (bore x outer diameter x width).

The JS suffix is not defined in the manufacturer’s catalogue, so load ratings, limiting speeds and mass are not shown for this bearing. If you need them for a design or life check, contact AIMS with the bearing number and we will confirm the figures with the supplier before you order.

A tapered roller bearing carries combined radial and axial load. The cone (inner ring and roller assembly) and the cup (outer ring) are separable, and the internal clearance is set at mounting by the axial position of the cone relative to the cup.

Where this product is used

• Industrial gearboxes and speed reducers
• Wheel hubs, axles and vehicle drive trains
• Transmissions and differentials
• Conveyor drives and general industrial machinery
• Equipment with combined radial and axial loads on one shaft

Features

• Tapered roller bearing in the 32000 series with a 25 mm bore
• The cone and cup are separable and the clearance is set at mounting; the bearing can be preloaded for higher rigidity and running accuracy
• Load ratings, limiting speeds and mass are not shown because this designation has no catalogue row: contact AIMS to confirm the figures before ordering

Key specifications

Selecting the right option

If you need published ratings for a bearing of this size, the standard 32005J in the same 25 x 47 x 15 mm size is listed with full catalogue figures on the NACHI metric J tapered roller bearings page. Check the full designation against the bearing you are replacing before you order.

Fitting and use

The internal clearance is set when you mount the bearing, by the axial position of the cone against the cup. The bearing can also be preloaded for higher rigidity and running accuracy, but too much preload raises heat and shortens bearing life, so follow the equipment maker’s setting.

Check the fit, clearance and preload with the equipment maker’s figures before ordering, and contact AIMS if you want a second opinion.
