FK Rod Ends & Bearings offers six grades of bearing products
for racing applications:

General Purpose — 2-piece style CM / CF; also available 2-pc ChromeMoly CMX

The ball rides on a formed portion of the mild steel body. Fairly high misalignment capability and good strength/cost ratio. Popular for linkage.

General Purpose — 3-piece style JM / JF

Three-piece style features a heat-treated race for the ball to ride on. Less misalignment capability than the CM / CF series. Similar in strength to the CM / CF series.

Specialty Racing Aluminum — 3-piece style ALJM / ALRSM

Made from 7075-T6 Aluminum, the ball rides on a heat-treated race; excellent for sprints and midgets, designed to save chassis in the event of a crash.

High Strength Chrome Moly or 17-4 PH Stainless Steel — 3-piece style JMX / JFX / PMX / SJM

These styles are very strong due to the use of heat-treated alloy steel, 52110 bearing steel ball. Rides on a hardened race for long life.

General Purpose Oversize Body — 3-piece style RSM

Oversize body gives extra strength; mild steel material allows a low cost part. The ball rides on a heat-treated race for longer life.

High Strength Chrome Moly or 17-4 PH Stainless Steel Oversize Body — 3-piece style RSMX / SRSM

Strongest parts available due to the use of a body that is one size larger than the bore. Material is heat-treated 4130 Chrome Moly, 52100 bearing steel ball rides on a heat-treated alloy race for long life.

All of the rod ends above feature a 52100 bearing steel ball that is precision-ground and hard-chrome plated.

If desired, all FK Bearing rod ends may be lined with aircraft-grade TEFLON between the ball and the race for a tighter initial fit and longer life due to the self-lubricating properties of the Teflon material. Some of the rod ends come standard with this liner (designated with the suffix "T") — please consult the catalog or our web-site for final determination.
