322 Series Medium-Heavy Single Row Tapered Roller Bearings Full Sizes & Complete Suffix Guide

We supply full range 322 series medium-heavy single row tapered roller bearings from 32203 to 32220, optimized moderate cross-section with standard contact angle balanced structure, capable of bearing balanced radial and axial combined loads, moderate impact shock and normal to medium high temperature industrial working environments. Made of high-purity GCr15 bearing steel with precision quenching & tempering heat treatment, these bearings deliver stable rigidity, low friction and long service life under continuous medium-heavy load operation. They are the universal bestseller for light/medium truck, construction, agricultural machinery aftermarket distributors, standard metric dimensions fully interchangeable with Timken, SKF, NTN original bearings, complete sizes permanently in stock for bulk wholesale mixed orders.

(Español: Suministramos toda la serie 322 rodamientos cónicos una fila carga media pesada 32203 hasta 32220, estructura equilibrada carga radial y axial, ideal para camiones ligeros, maquinaria agrícola y equipos de construcción, totalmente intercambiables con marcas internacionales.)

Balanced Contact Angle Medium-Heavy Reinforced Structure

322 series adopts moderate widened roller and raceway design plus standard medium contact angle, perfectly balance radial load and axial thrust capacity. Axial bearing performance better than light-duty 320/329 series, more compact, lower friction and cost-effective than extra heavy-duty 323 series. Super-finished roller surface reduces friction heat buildup, stable low-vibration continuous running for long-hour medium-load machinery, greatly extend overhaul cycle and cut maintenance spare parts cost for global wholesale buyers.

(Español: La serie 322 usa ángulo de contacto moderado, equilibra carga radial y axial, menor fricción y precio competitivo frente a la serie 323 para trabajos de carga media.)

Multiple Internal Clearance & Cage Configuration Options

All 322 series bearings adopt high purity GCr15 bearing steel via strict precision quenching heat treatment, covering standard CN, C3, C4 clearance grades to fit normal / medium-high / severe heat expansion working environments. Two mainstream cage solutions: stamped low-carbon steel cage for cost-effective mass bulk wholesale and medium speed equipment; solid machined brass cage M suffix for long continuous medium-high speed heavy-duty running with superior heat dissipation and wear resistance. Strict dimensional tolerance control guarantees seamless assembly matching for light commercial vehicle, agricultural and general construction machinery repair replacement.

Frequently Asked Questions About 322 Series Medium-Heavy Tapered Roller Bearings

1.Can I mix 322 series with other bearing types in one wholesale bulk order?

Mixed container loading is fully supported. You can combine different 322 series sizes, clearance grades, cage materials together with deep groove ball bearings, pillow block bearings, other tapered roller series (32900/33000/32000/32300) in one shipment to cut down ocean freight cost, flexible low minimum order quantity for mixed wholesale orders.

(Español: Aceptamos carga mixta en contenedor con otros tipos de rodamientos, MOQ flexible para pedidos mayoristas combinados.)

2.Do you offer OEM private label & custom export packaging service for 322 series tapered roller bearings?

Yes, full OEM customization available for all 322 series models. We provide neutral export cartons, custom color boxes, private brand logo printing, customized product labels. Brass cage, P5 precision and high-temperature treated special medium-heavy tapered roller bearings all support OEM bulk packaging orders.

(Español: Ofrecemos servicio OEM con empaques personalizados y logo propio para toda la serie 322 de rodamientos cónicos carga media pesada.)

3.Are your 322 series tapered roller bearings fully interchangeable with Timken / SKF / NTN original bearings?

All 322 series tapered roller bearings strictly comply with ISO international metric dimensional standards, 100% dimension interchangeable with mainstream global brand original tapered roller bearings. No mechanical modification required during light truck axle, agricultural and small construction machinery maintenance replacement, perfectly matching original medium-load assembly structure.

(Español: Todos nuestros rodamientos serie 322 cumplen norma ISO métrica, intercambiables 100% con Timken, SKF y NTN sin modificaciones mecánicas.)

4.What is your stock & production delivery lead time for 322 series bearings?

Standard 322 models (32203~32220) CN/C3 clearance with steel cages are permanently stocked in warehouse, ready to ship within 3-7 working days after deposit payment. Custom brass cage M suffix, P5 high precision and C4 oversized clearance 322 medium-heavy bearings require 15-28 days dedicated production lead time.

(Español: Modelos estándar en stock envío 3-7 días; modelos personalizados jaula latón o precisión P5 requieren 15-28 días de fabricación.)

5.Which suffix configuration is most recommended for light truck axles, mini excavators and farm tractor medium load working conditions?

For light-duty truck wheel hubs, mini excavators and agricultural tractors with continuous medium impact load running, our best-selling recommended combo is 322XX C3 standard steel cage bearing. The C3 enlarged clearance offsets thermal expansion generated by long-hour highway hauling and farm equipment uninterrupted operation, standard steel cage balances cost and durability for large-volume aftermarket vehicle & farm machinery parts wholesale replacement orders worldwide.

(Español: Para ejes de camión ligero, mini excavadoras y tractores agrícolas recomendamos rodamientos serie 322 C3 por holgura ampliada resistente al calor y cargas moderadas.)
