Stieber bearings are a type of rolling bearing. Spherical alloy steel balls are installed between the inner and outer steel rings to reduce friction during power transmission and improve mechanical power transmission efficiency through rolling motion. Ball bearings cannot withstand heavy loads and are common in light industrial machinery. Ball bearings are also called ball bearings.

Stieber bearing applications

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

Stieber bearing operating requirements

For bearing configurations with heavy loads, harsh operating conditions, or special sealing requirements, self-aligning roller bearings with built-in contact seals 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 misalignment angle is 0.5°, and the operating temperature range is -20℃ to 110℃. The bearings are pre-filled with an appropriate amount of lithium-based anti-rust grease; additional grease can be added upon user request. Based on the presence or absence of flanges 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 features an inner ring without flanges and uses a stamped steel cage, while the CA type features flanges 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 consist of drum-shaped rollers assembled between an inner ring with two raceways and an outer ring with spherical raceways.

Stieber bearing packaging

Packaging consists of inner and outer packaging. After manufacturing and passing inspection, bearings are cleaned and treated for rust prevention before being placed in inner packaging. This aims to prevent water, moisture, dust, and impact, maintain bearing quality and precision, and facilitate use and sales. Inner bearing 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. Simple packaging is adopted based on mutual agreement and 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 include polyethylene plastic tubes (boxes), kraft paper, plain and creased 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 materials must pass corrosion resistance tests.
