FAQs About Insert Bearings from BKZ Industry

Q1. What Types of Seals Are Available for Insert Bearings?

BKZ insert bearings are available with several seal options, including single seals, double seals, triple-lip seals, and metal shields. The right seal depends on your operating environment, such as exposure to dust or moisture, running speed, and temperature conditions. You can contact us to send your requirements to customize.

Standard BKZ insert bearings typically operate within a temperature range of –20°C to +120°C. For higher or more demanding temperature conditions, special grease or materials can be used to extend performance limits.

Choosing the right insert bearing depends on factors such as shaft diameter, radial and axial load requirements, operating speed, environmental conditions, and the preferred locking and seal type. For the best results, BKZ recommends consulting with a bearing specialist or manufacturer.

Certain insert bearing features, such as seals, lubrication options, and materials, can be customized depending on the application requirements.

Yes, insert bearings can be used in wet or corrosive environments by selecting stainless steel bearings or bearings with corrosion-resistant coatings and enhanced sealing to protect against moisture and chemical exposure.

Insert bearings are compatible with various housing types, including pillow block housings, flanged housings, take-up housings, and hanger housings.
