The HSPA series housings, made from high-quality cast steel, showcase an undivided construction, including covers and labyrinth rings. Their precise rail framework guides the housings through rails. The tension drum bearings are predominantly supplied in fixed bearing configuration, effectively compensating for axial expansions of the shaft and supporting structure through the controlled play between the rail and housing guide. heavy duty housings made from steel
- Product Name: HSPA Take-Up Housings
- Product Description: HSPA take-up housings are specifically designed to accommodate the elongation of belts or chains in various applications, ensuring proper tension and alignment. These non-split housings are designed for self-aligning roller bearings, with shaft diameters ranging from 60 mm to 670 mm. Sealing is achieved through labyrinth rings, offering enhanced protection against contaminants. The bearing seat is precision-machined to G7 tolerance, ensuring high accuracy. The standard housings are made from GS45 steel casting, with alternative materials and sealing options available upon request.
These robust, compact housings are made from GS45 cast steel (with covers in grey cast iron) and are ideal for applications requiring high stiffness and the ability to support heavy radial loads in all directions. Their narrow profile makes them suitable for installation in tight spaces, and the machined base ends ensure precise alignment. HSPA housings are painted black (RAL 9005), with rust protection applied to unpainted surfaces. Repainting with standard coatings is possible if required.
Ensure precise mounting of HSPA and HBND housings using advanced tools and methods that meet specified requirements. Follow ISO-4017 standards for tightening cover bolts to specified torque values in table 5. The adapter ring, responsible for securing the labyrinth ring, features plain holes for mounting and threaded holes for dismounting.

Sturdy and space-efficient, HSPA plummer block housings and HBND take-up housings offer robust support for heavy radial loads in all directions. With a narrow design and machined base ends for easy alignment, these housings are equipped with eye bolts for safe handling. Crafted from spheroidal graphite cast iron, their covers are made of grey cast iron. Painted in blue (RAL 5007) with solvent-based alkyd/acryl paint, they meet ISO 12944-2 corrosion protection standards in C2 category environments. The paint resists various substances, and housings can be repainted with ease. Unpainted surfaces are safeguarded by a solventless rust inhibitor.
HSPA plummer block and HBND take-up housings feature standard labyrinth seals, providing effective protection. They are compatible with sealed spherical roller bearings and offer variants for taconite heavy-duty seals. The grey cast iron labyrinth seal, mounted on the shaft, forms a multi-stage axial labyrinth with housing cover seal grooves
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
GS45 is an unalloyed cast steel commonly used in general mechanical engineering. Due to its higher carbon content, its weldability is lower compared to GS38. GS45 represents a castable variant of structural steel C45.GS45 is suitable for various applications, including frame constructions, building structures, (rear) axles, and bearing housings.
