SNR Self-Aligning Bearing Units: Versatile Industrial Solutions
The SNR self-aligning bearing unit range offers unparalleled versatility with over 40,000 possible combinations. Designed to meet the demands of the majority of industrial applications, these units provide a high-quality, cost-effective solution for power transmission and machinery maintenance. At its core, the SNR system is designed for simplicity. Installing a self-aligning bearing unit is straightforward, requiring no specialist technical skills. The modular "plug and play" design consists of two primary components: The Housing + The Bearing Insert.
The Anatomy of SNR Housed Bearings Each unit is a precision-matched combination of a housing and a bearing insert, engineered to provide the ideal solution for specific environmental and mechanical loads.
1. High-Performance SNR housings The SNR range stands out due to its diverse choice of designs and materials. We offer a comprehensive selection of housing types to suit any mounting requirement:
- Pillow Block Housings: For supporting shafts parallel to the mounting surface.
- Flanged Units: (2-bolt, 3-bolt, and 4-bolt options) for mounting on vertical surfaces.
- Take-up Housings: Ideal for conveyor tensioning applications.
- Cartridge and Hanger Housings: For specialised industrial machinery.
Durability Across Materials:
SNR housings are manufactured in a variety of materials to suit your specific operating environment:
- Grey Cast Iron: For standard heavy-duty industrial use.
- Pressed Steel: For lightweight or economical applications.
- Stainless Steel & Thermoplastic: Essential for food processing, pharmaceutical, or corrosive environments.
2. Precision Bearing Inserts SNR bearing inserts feature a spherical outer diameter, designed around the proven internal geometry of 62 and 63 series single-row deep groove ball bearings. The housing features a matching spherical seat, allowing the insert to sit securely while maintaining the ability to pivot. Key features include:
- Self-Alignment: The unit can compensate for static misalignment of the shaft in all directions.
- Maintenance-Free Options: We offer sealed, lubricated-for-life inserts from NTN-SNR, reducing downtime and maintenance costs.
- Simple Mounting: Various fixing methods on the extended inner ring (such as grub screws or eccentric locking collars) ensure a secure fit to the shaft with minimal effort.
