How the BT2B328130 model number is decoded
Numbering for double-row tapered bearings is works-specific: BT2B 328130 denotes the envelope (260 mm bore, 480 mm OD, 284 mm width) and the suffix the internal design — two bearings with the same base number but different variants are not interchangeable without checking the variant meaning. Lubrication planning: two roller rows inside a 480 mm OD envelope sweep a large contact area per revolution; oil circulation or a defined grease-relubrication interval should be sized against the 210.0 kg assembly mass. The 110.0 mm radial section height ((480−260)/2) and 284 mm width frame a unit whose two rows share reversing thrust; keep the equivalent load P against the pair rating C 4330 kN, never against a single-row figure. Assembly datum check: verify the 284 mm width against the drawing before clamping — the width is the assembled result and the quickest field check that the correct execution of BT2B328130 is on the shaft. Documentation tip: record the TDO variant with the machine BOM entry for BT2B328130; at overhaul the variant code is what lets the supplier reproduce the original clearance setting. TDO mounting: the double cup is clamped in the housing and the two cones take interference on the 260 mm shaft; press force goes through the cone faces only — driving through the rollers brinells both raceways at once.SKF BT2B 328130 belongs to the SKF TDO double-row range — the 260 mm bore entry with a 480 mm outside diameter and 284 mm overall width, built for roll-neck and heavy-gearbox duty.
Typical equipment & failure modes
Common applications
- rolling-mill roll-neck bearings
- heavy-duty rolling-mill gearboxes
- large crusher and mineral-processing drives
- large crusher and mineral-processing drives
Known failure patterns
- brinelling of both raceways when mounting force is transmitted through the roller complement
- axial clamping ring bolt relaxation that lets the clearance-set rows walk apart under reversing thrust
- pressed-steel cage wear or fracture after prolonged running above the limiting speed
- rib-roller contact scoring from loss of the EP additive film
- mounting score marks when the cone is cocked over the shaft keyway or a burr
Selection pitfalls — read before you substitute
- Never adjust the clearance of BT2B328130 in the field: the two rows are set by ground spacers at the factory, and shim experiments on a 210.0 kg assembly usually end in overheated rows.
- Lifting BT2B328130 by one ring separates the assembly; sling through the 260 mm bore or use the shaft as the lifting member.
- Do not mix components between units of the same BT2B 328130 base number: cones, cups and spacers are matched per serial — interchange only complete assemblies.
- The 4330/7350 kN ratings are SKF catalogue 17000 values for this execution; SKF can revise internal geometry without changing the order number, so keep the catalogue version (PUB BU/P1 17000/1 EN, 2018) with the specification.
- Quote the full SKF BT2B 328130 designation when purchasing — base-number-only orders are ambiguous across executions and variants.
Frequently asked questions
What are the dimensions and catalogue data of BT2B328130?
The SKF BT2B 328130 is a double-row tapered roller bearing of TDO design with 260 mm bore, 480 mm outer diameter and 284 mm overall width (10.236 × 18.898 × 11.181 in). From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 4330 kN, C0 7350 kN, fatigue load limit Pu 600 kN, mass about 210.00 kg.
What does the TDO variant code on BT2B328130 mean?
Double-row tapered bearings of this size follow SKF works numbering: the base number BT2B 328130 fixes the 260×480×284 mm envelope, and the TDO code identifies the internal design variant — spacer execution, rib detail and clearance class. Same-envelope units under a different variant are not interchangeable without checking the variant meaning.
Why does the catalogue list no speed rating for BT2B328130?
Bearings of this size class run in slow, heavily loaded machinery where the permissible speed is set by the application heat balance rather than a universal table value. Plan lubrication and cooling against the 210.0 kg assembly mass and instrument the first run with temperature logging.
Can components of BT2B328130 be interchanged with another unit of the same base number?
No — cones, cups and spacers of a double-row set are matched per serial and the clearance is set by selective grinding at the factory. Replace BT2B328130 as a complete assembly in the same TDO variant.
How does BT2B328130 react axial load?
The TDO design works as a fixed X arrangement: one double cup with two cones locates the shaft in both axial directions, with load shared between the two rows according to the factory-set clearance.
