OTT Bearing (Zhejiang Tongtao Bearing Co., Ltd.) exhibited at AAPEX 2026, the premier automotive aftermarket products expo, at the Venetian Expo in Las Vegas.

Booth 21641 — where we showed our complete wheel hub bearing range, including our high-performance trailer and recreational vehicle bearing lines.

What We Showcased

AAPEX is the largest gathering of automotive aftermarket professionals in the Americas, and the perfect venue to present OTT's full bearing capabilities:

Wheel hub bearings for trailers and RVs — Our featured product line at the show. Towing applications demand bearings that handle sustained high loads, heat buildup, and occasional water exposure (boat trailers). OTT's tapered roller bearings and pre-assembled hub units are built for exactly these conditions:

  • High-load tapered roller designs for utility, boat, and horse trailers
  • Pre-lubricated, sealed hub assemblies for recreational vehicles
  • Cross-referenced to Timken, BCA, and National part numbers
  • Carbonitriding heat treatment for 5–10x extended service life

Automotive wheel hub bearings — Our core product line covering 40+ vehicle brands. Double-row angular contact ball bearings, tapered roller wheel bearings, and Generation 1/2/3 hub units. Over 200 models with cross-references to SKF, FAG, KOYO, NTN, NSK, and SNR.

Complete automotive bearing range — Alternator bearings, tensioner/idler pulley bearings, AC compressor clutch bearings, and go-kart bearings. One supplier, one quality standard, full product coverage.

Why Aftermarket Buyers Choose OTT

For aftermarket distributors and WD (warehouse distributor) buyers we met at AAPEX, here's why OTT stands out:

Factory direct — We are the manufacturer, not a trading company. Our 20,000 m² factory in Jiashan operates 24 production lines with 20 million sets annual capacity. This means better pricing, more consistent quality, and faster response to your needs.

Proven quality — IATF 16949 and ISO 14001 certified. 130+ patents. Our bearings have passed a 1,004-hour continuous endurance test commissioned by a Russian OEM client — one of the most demanding bearing qualification tests in the industry.

Full OEM support — Custom branding, packaging, seal types, grease specifications, and tolerance grades (P6/P5). Whether you need 1,000 pieces or 100,000 pieces per month, we scale with your business.
