Decoding FAG C4192-XL-K30-M1B
- C 41Series
- Toroidal roller bearings, C 41 series. Series differ in outside diameter and width even when the bore is the same.
- 92Bore
- Bore 460 mm (92 × 5).
- XL-K30-M1BSuffix
- FAG suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
C 4192 is the standard ISO basic designation, which sets the bearing type, series and bore.

When radial and axial forces arrive at the same time, toroidal roller bearings offer a practical way to carry them. Their rollers have a toroidal profile and run on spherical raceways, which allows the bearing to absorb misalignment. MR Industrial Accessories LLC supplies this FAG line to maintenance and purchasing teams across the United States and in several Latin American countries, for demanding equipment in mining, steel, cement and similar operations.
The part number tells you what you are holding. Take C41/500-XL-K30-M1B: the C at the front marks the toroidal roller family, 41/500 is the size, XL points to the optimized current design, K30 means a tapered bore with 1:30 taper, and M1B is the machined brass cage, roller-centered. Reading those suffixes correctly is the first step in choosing the right variant for a given mounting.
These bearings show up in heavy machinery: large gearboxes, mills, crushers, roller presses and continuous casting machines. Because they tolerate combined loads and misalignment, they suit transmission shafts that deflect, where other bearing types would suffer fatigue. They also work in oscillating motion or in slow-turning, heavily loaded positions.
Selection comes down to load size and direction, rotational speed and the surrounding conditions. A K30 bore needs a tapered shaft or an adapter sleeve, with a controlled interference fit. Lubrication follows temperature and speed: grease for low speed, oil for higher regimes. Initial alignment is less critical than with some other types, but seating and internal clearance should still be checked after mounting.
Interchange is possible with other brands that use the same dimensional and suffix nomenclature, though internal tolerances, cage materials and surface treatments can differ. When replacing a bearing, confirm the full part number and the service conditions. MR Industrial Accessories LLC supplies FAG and can advise on interchangeability without compromising equipment performance.

Frequently asked questions
- FAG C4192-XL-K30-M1B bearing: what are its dimensions?
- FAG C4192-XL-K30-M1B measures 460 mm across the bore and 760 mm across the outside diameter; its width is 300 mm (460 x 760 x 300 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation C 4192.
- What does the K30 suffix mean on a FAG toroidal bearing?
- K30 indicates a tapered bore with a 1:30 taper. The bearing mounts on a tapered shaft or with an adapter sleeve, giving a controlled interference fit. Check the shaft diameter and taper before installation.
- When should I use a toroidal bearing instead of a cylindrical roller bearing?
- A toroidal bearing carries combined radial and axial loads and tolerates misalignment. A cylindrical roller bearing is chosen for radial loads only when alignment is precise. The decision depends on the load case and mounting conditions.
- Which lubricant works for a FAG toroidal bearing?
- It depends on speed, temperature and environment. Lithium complex grease suits low speeds and moderate temperatures; circulating oil is recommended for high speeds or elevated temperatures. Send your application data on WhatsApp for guidance.
