Drum inner bearing with inner position in the side flange. Conventional drum inner bearings are often manufactured with "flanged" bearing housings. With larger loads, this type of housing is not sufficient and is replaced by individual custom-made solutions. Our RSFH housings are standardized inner bearings for high loads that act directly in the drum side walls.
- Product Name: RSFH Drum Inner Bearings
- Product Description: The RSFH drum inner bearings are specifically designed for use in conveyor drum assemblies, but can also be applied in any other suitable application. The bearing seat for the spherical roller bearings or spherical ball bearings is located directly in the recess, allowing the load to be directly transmitted to the drum shell. The recess is machined to an H8 tolerance. RSFH housings are made from grey cast iron GG20, ensuring high durability and strength. These housings are available with either a felt seal or a Taconite seal, making them well-suited for most industrial applications.
RSFH Flange bearing housings are designed for accommodating self-aligning ball or roller bearings with a clamping sleeve. Equipped with a Labyrinth- and OSM-seal, these housings allow the usage in difficult environments. The option to choose between a closed cover (A-Type) or an open cover (B-Type) adds versatility to their applications.

Our drum inner bearings are stocked up to a shaft size of 60mm with a felt seal + an additional groove for gamma rings. From a shaft diameter of 70mm, you will receive the inner bearing with a combination seal consisting of a radial shaft seal and an axial labyrinth seal. These housings are designed with a felt seal on the flange side
RSFH housings are standardized inner bearings for high loads that act directly in the drum side walls.
Labyrinth seals are highly effective sealing systems used in a variety of applications to prevent the ingress of dust, dirt, and moisture into rotating machine parts. With their intricate and efficient design, labyrinth seals provide reliable sealing and help extend the lifespan of bearings, shafts, and other rotating components
GG20 offers excellent machinability and is highly heat and corrosion-resistant. Additionally, this material provides outstanding finishing capabilities and exhibits excellent properties concerning sound and vibration damping. However, its strength and wear resistance are limited.
