Bearing housings
The bearing housings available in the Marat store are products of the highest quality. Based on extensive experience gathered over more than 30 years of operation, we know exactly what properties manufacturer-produced housings must possess. The product range offered by Marat includes bearing housings with diverse technical specifications, manufactured by industry-esteemed brands such as SKF, PTI, NTN, and SNR—the latter being a combination of two highly regarded names in the sector.
Why are bearing housings used?
A bearing housing is essentially an enclosure or mount for a bearing. It is a complete structural component designed to protect and support the bearing. Firstly, the housing enables high-precision bearing mounting. Secondly, it safeguards the bearing against contamination and mechanical damage. Thirdly, it retains the lubricant. Utilizing bearing housings enhances operational safety, simplifies equipment maintenance, and—above all—maximizes the efficiency and performance of the bearings.
Housed bearings operate reliably and stably, ensure excellent heat dissipation, and offer above-average durability. The benefits of using high-quality bearing housings translate into extended maintenance intervals and, simultaneously, a prolonged period of satisfactory equipment utilization.
Bearing housing - types
Bearing housings are manufactured from cast iron, stainless steel, or engineering plastics. The housings available in Marat's offer are primarily cast iron and steel variants, characterized by heavy-duty strength.
The variety within our product range demonstrates how many different configurations a bearing housing can take. In practice, only a few types of these accessories find the widest application. These include plummer (pillow) block housings, flanged housings, and take-up housings.
One of the most critical classifications distinguishes between split and non-split housings. A split bearing housing guarantees significantly easier access to the interior, allowing for simpler bearing lubrication. In the event of damage, the housing can be replaced very quickly, or an individual component can be repaired. This type of bearing housing is commonly used with spherical roller bearings, ball bearings, and cylindrical roller bearings.
A non-split housing also has its advantages—its mounting process is much simpler than that of a split housing. However, remember that if any sub-component is damaged, the entire housing must be replaced. Cylindrical roller bearings, tapered roller bearings, and spherical roller bearings interface best with this type of housing. Non-split housings are most frequently used in applications subjected to exceptionally heavy loads.
Which bearing housing will be suitable?
A bearing housing is a proven method to maximize bearing efficiency, service life, and cost-effective maintenance. The Marat store's offer abounds in tried-and-tested solutions from the top manufacturers in the industry. Products are available in cast iron or steel configurations, including variants with felt seals. We invite you to select the appropriate housings based on the scope of design designs and dimensions—our team is ready to assist you if needed.
Other categories also feature additional accessories responsible for bearing locating and secondary protection: locating rings and end covers. If the objective of your purchase is a ready-to-install housed bearing unit, we invite you to explore the product range in the Bearing units category.
