Germany THORMAS bearings THORMAS models THORMAS prices

THORMAS bearings are available in two structures: cylindrical bore and tapered bore. Cage materials include steel sheets and synthetic resins. Their characteristic is that the outer ring raceway is spherical, providing automatic self-alignment to compensate for errors caused by misalignment and shaft deflection; however, the relative inclination between the inner and outer rings must not exceed 3 degrees.

THORMAS bearing applications

Self-aligning ball bearings are suitable for heavy loads and impact loads, precision instruments, low-noise motors, automobiles, motorcycles, metallurgy, rolling mills, mining, petroleum, papermaking, cement, sugar refining, and other industries as well as general machinery.

THORMAS bearing operating requirements

For bearing configurations with heavy loads, harsh operating conditions, or special sealing requirements, built-in contact-type sealed self-aligning roller bearings can be used. The external dimensions of these bearings are identical to non-sealed bearings, allowing them to replace non-sealed bearings in many applications. The allowable self-alignment angle is 0.5°, and the operating temperature range is -20°C to 110°C. The bearings are pre-filled with an appropriate amount of lithium-based anti-rust lubricating grease, and additional grease can be added upon user request. Based on the presence or absence of ribs on the inner ring and the type of cage used, they are divided into two basic types: C type and CA type. The C type bearing features no ribs on the inner ring and uses a stamped steel cage, while the CA type bearing features ribs on both sides of the inner ring and uses a machined solid cage. This type of bearing is particularly suitable for operation under heavy loads or vibratory loads. Self-aligning roller bearings are equipped with barrel-shaped rollers between the inner ring with two raceways and the outer ring with a spherical raceway.

THORMAS bearing packaging

Packaging is divided into inner and outer packaging. After manufacturing and passing inspection, bearings are cleaned and treated for rust prevention, then placed in inner packaging to achieve waterproofing, moisture-proofing, dust-proofing, and shock protection, maintaining bearing quality and precision while facilitating use and sales. Bearing inner packaging is classified into three categories based on the rust prevention period: (1) Short-term rust prevention packaging: Rust prevention period of 3 to 6 months, suitable for bearings shipped in large quantities to the same customer and put into use within a short period. By mutual agreement, simple packaging is adopted for ease of use. (2) General rust prevention packaging: Rust prevention period of one year, suitable for general-purpose bearings. (3) Long-term rust prevention packaging: Rust prevention period of two years, suitable for specialized and precision bearings. Inner packaging materials for bearings include polyethylene plastic tubes (boxes), kraft paper, plain and crepe polyethylene composite paper, paper boxes, polyethylene or polyethylene plastic film, nylon fastening straps or plastic woven fastening straps, waterproof high-strength plastic straps, jute bags, etc. All the above materials must ensure that the corrosion resistance performance tests are passed.
