Timken 22216EJW33 Spherical Roller Bearing
Description
A 80 mm bore spherical roller bearing for heavy radial loads and misalignment
The Timken 22216EJW33 is a radial spherical roller bearing from the Timken EJ range, with a cylindrical 80 mm bore, 140 mm outside diameter and 33 mm width. The EJ style uses a hardened, land-riding stamped-steel cage (one per row) and, per the catalogue, offers higher load ratings, higher thermal speed ratings and lower operating temperatures than the previous Timken offering. The W33 suffix means a lubrication groove and three oil holes in the outer ring, so grease or oil can be fed through a single lubrication fitting without machining a channel in the housing bore. Spherical roller bearings accommodate shaft misalignment and are widely used in pumps, fans, gearboxes, conveyors and general industrial machinery.

Mounting and ordering notes
The catalogue lists the tapered-bore version as 22216K, used with adapter sleeve H316 or withdrawal sleeve AH316. Internal clearance and other options such as C3 are added as suffixes and must be stated when ordering. Dynamic and static ratings, factors and speeds above are the catalogue values for this part number and should be used with the catalogue life and speed calculations rather than alone.
What to confirm before ordering
Confirm the bore type (cylindrical or tapered), clearance class, lubrication method, operating speed, loads and whether the application is vibratory (W800 designs exist for that). Another Timken part on this site is the Timken 32206 tapered roller bearing; more are listed under Electric Motors, Pumps and Turbines.
Documents and quotation
The attached Timken Spherical Roller Bearing Catalog (Order No. 10446, 06-24) contains the dimension, rating and speed tables. State the part number, clearance class and quantity when requesting a quotation.

About brand
The tapered roller bearing and the Timken name have gone together since the company began in 1899. Timken, based in North Canton, USA, makes bearings and power transmission products for industrial machinery, vehicles and heavy equipment. Seven Star LLC lists the Timken 32206 tapered roller bearing and supplies Timken bearings to maintenance departments and workshops in Oman and the GCC.
Timken tapered roller bearings
A tapered roller bearing carries radial load and thrust in one direction together, which is why it is used in gearboxes, pump and fan shafts, wheel hubs and conveyor drives, normally in opposed pairs. The 32206 is a metric single-row bearing: 30 mm bore, 62 mm outside diameter and 21.25 mm overall width. It consists of a cone assembly and a separate cup.
Ordering Timken bearings: what we need
Give the complete part number stamped on the bearing, including any prefix and suffix. Inch-series Timken bearings have separate numbers for cone and cup, so quote both. If the marking is worn, measure bore, outside diameter and width and tell us the machine and shaft position. State the quantity and any precision class or special clearance required.
