About this product line

About Single-Row Tapered Roller Bearings

OTT single-row tapered roller bearings are manufactured from GCr15 bearing steel with precision-ground raceways, available in both metric (ISO 355 / DIN 720) and inch (ABMA) series. The metric series covers 30000, 32000, 33000, and 31000 families (d = 20-150 mm), while the inch series covers LM, HM, and standard AFBMA cone/cup pairs (d from 0.5" to 2.5"). All bearings feature optimized roller-raceway contact geometry for high radial and axial load capacity, with cage options in steel, brass, or polyamide. Dynamic load ratings up to 300 kN. Precision grades P0 standard, P6/P5 available on request. Cross-referenced to Timken, SKF, FAG, NTN, KOYO, and NSK catalogues.

FAQ

Frequently asked questions

What is the difference between metric and inch tapered roller bearings?

Metric tapered roller bearings follow ISO 355 / DIN 720 standards with dimensions in millimetres (e.g. 30204, 32208, 33212). Inch series follow ABMA standards with dimensions in inches, identified by cone (inner ring + rollers + cage) and cup (outer ring) part numbers (e.g. LM11949/LM11910, HM218248/HM218210). OTT supplies both series from the same factory with full interchangeability to Timken and SKF dimensions.

How do I select the correct tapered roller bearing size?

Tapered roller bearing selection depends on bore diameter (d), outer diameter (D), overall width (T or B+C), and required load capacity (Cr/Cor). For replacements, match the OEM part number or provide d x D x T dimensions. OTT engineers can assist with load calculations and cross-reference lookups. Contact us with your application details for a recommendation.

What Timken equivalent numbers does OTT tapered roller bearings cover?

OTT inch-series tapered roller bearings are fully interchangeable with Timken inch cone/cup pairs including LM11949/10, LM12749/10, LM48548/10, LM78349/10, HM218248/10, 25580/25520, 29590/29520, and 100+ additional models. All dimensional tolerances match ABMA Class 4 (equivalent to AFBMA Grade 4 / ISO P0). Contact us with your Timken part number for confirmation.

What is the typical load capacity range for OTT tapered roller bearings?

OTT tapered roller bearings range from Cr = 14 kN (30202, d=15mm) to Cr = 300+ kN for heavy-duty sizes. The metric 32216 (d=80mm) carries Cr = 200 kN, and the inch HM218248 (d=88.9mm) carries Cr = 223 kN. OTT can provide full load rating data and L10 life calculations for your application.

Can OTT supply matched bearing pairs for pre-loaded applications?

Yes. OTT supplies factory-matched tapered roller bearing pairs for face-to-face (DF), back-to-back (DB), and tandem (DT) arrangements. Matched pairs are pre-selected for consistent preload and are commonly used in automotive wheel hub applications, precision machine tool spindles, and differential assemblies.
