Germany BOLLFILTER bearings BOLLFILTER models BOLLFILTER prices

BOLLFILTER bearings can simultaneously withstand radial and axial loads. They can operate at higher speeds. The greater the contact angle, the higher the axial load capacity. The contact angle is the angle between the line connecting the contact points of the ball and raceway in the radial plane and the perpendicular to the bearing axis. High-precision and high-speed bearings typically use a 15 degree contact angle. Under axial force, the contact angle increases.

BOLLFILTER bearing applications

Self-aligning ball bearings are suitable for heavy loads and shock 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.

BOLLFILTER bearing operating requirements

For 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, and they can 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 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 no flanges on the inner ring 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 vibration 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.

BOLLFILTER 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, and facilitating use and sales. 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 bulk shipments to the same customer for immediate use. 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 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 above materials must pass corrosion resistance tests.
