This NACHI range covers 88 single row metric tapered roller bearings with the J suffix, from 15 to 140 mm bore (outer diameters 35 to 250 mm, overall widths 11.75 to 71.75 mm), in the 30200 (19), 30300 (16), 32000 (21), 32200 (19) and 32300 (13) series. Choose the size from the drop-down: each size has its own load ratings, speed limits, mass and shoulder dimensions in the Model Details.

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. A single row bearing takes axial load in one direction, so for axial load both ways fit a pair, face-to-face or back-to-back.

The J suffix (E prefix and J suffix in the catalogue designation, for example E30204J) means the bearing complies with ISO standards in sub-unit dimensions, so the cone and cup follow the ISO dimension plan and are exchangeable within the NACHI J range.

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

  • Single row tapered roller bearings for combined radial and axial load; a pair mounted face-to-face or back-to-back carries axial load in both directions
  • Separable cone and cup: the clearance is set at mounting by the axial position of the cone against the cup, and the bearing can be preloaded for higher rigidity and running accuracy
  • J suffix: ISO sub-unit dimensions, with the cone and cup exchangeable within the NACHI J range
  • Inner ring rib designed to guide the rollers and reduce heat build-up where the roller end meets the rib
  • Basic dynamic load ratings from 15.8 to 636 kN and limiting speeds from 1,500 to 12,000 rpm on grease, shown for every size
  • Constant e, axial load factors, load centre, mass and shoulder dimensions listed for each size in the Model Details

Selecting the right option

The first three digits of the number give the series, which sets the outside diameter and width for a given bore. At a 50 mm bore, for example, the 32010J is 80 x 20 mm with Cr 65.7 kN, the 30210J is 90 x 21.75 mm with Cr 76.5 kN, the 32210J is 90 x 24.75 mm with Cr 85 kN, the 30310J is 110 x 29.25 mm with Cr 137 kN and the 32310J is 110 x 42.25 mm with Cr 176 kN. Pick the series that fits the housing, then check the load and speed.

Check the full designation, including the J. For the 32000 and 32200 series, the catalogue gives different cone width B, cup width C and overall width T for bearings without the E prefix and J suffix, so a bearing of the same number without the J is not necessarily the same size.

To work out the equivalent dynamic load Pr for a single bearing: where Fa/Fr is at or below e, Pr = Fr; above e, Pr = 0.4 x Fr + Y1 x Fa. The e and Y1 values for each size are in the Model Details.

Fitting and use

A radial load on a single row tapered roller bearing creates an induced axial load, Fa' = Fr / (2 x Y1), which tries to separate the cone and cup. It is normally balanced by mounting two bearings as a pair or as a multi-row set, so work out the axial load on each bearing, not just the one that carries the thrust.

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.

Limiting speeds are given for grease and for oil lubrication. Check the load and speed against the figures for your size, apply a suitable safety factor and contact AIMS if you want a second opinion before ordering.

Product Highlights −

This NACHI range covers 88 single row metric tapered roller bearings with the J suffix, from 15 to 140 mm bore (outer diameters 35 to 250 mm, overall widths 11.75 to 71.75 mm), in the 30200 (19), 30300 (16), 32000 (21), 32200 (19) and 32300 (13) series. Choose the size from the drop-down: each size has its own load ratings, speed limits, mass and shoulder dimensions in the Model Details.

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. A single row bearing takes axial load in one direction, so for axial load both ways fit a pair, face-to-face or back-to-back.

The J suffix (E prefix and J suffix in the catalogue designation, for example E30204J) means the bearing complies with ISO standards in sub-unit dimensions, so the cone and cup follow the ISO dimension plan and are exchangeable within the NACHI J range.
