The SNGH pillow block housings offer a high degree of versatility as they are fully interchangeable with various series including SN, SNE, SNA, SNH, SNL, SNU, and SNV. Adhering to the DIN 736-739 standard, these housings boast main dimensions that meet rigorous industry specifications. The bearing seat, crafted to the G7 tolerance class, functions as a floating bearing. Additionally, for those seeking a secure bearing arrangement, the inclusion of locating rings of type FR on both sides provides a reliable solution.

Unleash the power of SNGH housings – precision in every detail. From unique marking pins to simplified alignment, our design ensures efficiency. Achieve dead-level surfaces and avoid confusion with matching running numbers. Enhanced load-bearing, optimized radius, and larger bolts showcase robust construction. Efficient heat dissipation guarantees durability. Experience the SNGH difference – where meticulous engineering meets unmatched functionality.
You can choose between different Seal arrangements. TS-Rings are labyrinth-seals for high-speed, max temperature of 200°C and bigger particles. If it comes to operation under humidity conditions you have to choose Taconite seal like our TAC - Seal for excample
Variants include housings made of different materials, alternative attachment bolt hole configurations, different bearing seat tolerance classes, and modifications for special applications
TSNO seals are used for sealing against internal media or external contaminants. They are similar to DIN 3760 with adapted outer diameters. TSNO seals fit into sealing grooves of our SNGH and SFCM housings. Standard TSNO seals are manufactured with an elastomer part, a metal reinforcement ring, and a spring. Maximum peripheral speed: 20 m/s, maximum operating temperature: 180°C
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.
