Extreme Bearing B.V. products

Extreme Bearing offers specialized split plummer block bearing units crafted from AISI 316 marine-grade stainless steel. These units are designed to withstand harsh environments and challenging conditions, making them suitable for demanding applications. The EBL series features split housings for easy replacement, compatible with standard plummer block dimensions such as SNHF, SNL, and others. This modular design accommodates various bearings, seals, and lubrication methods. The stainless steel base enhances robustness and heat dissipation, reducing operational temperatures and extending the lifespan of the components. Offering flexibility, the units support a range of sealing options, from oil seals to labyrinth seals. Key features include a grease escape hole with a non-return valve and optional polished finishes for high hygiene demands, making these units versatile and efficient.

The SS-316 double roller bearing units are engineered for demanding applications in corrosive environments due to their type 316 stainless steel construction, which offers enhanced protection against rust and chemical damage, including seawater. These bearings incorporate self-aligning double row ball bearings, significantly increasing load capacity by up to five times. The housing is designed for harsh conditions and can accommodate single or double row spherical roller bearings. The units also employ a perfect concentric fit on shafts using an adapter sleeve, reducing risks of shaft cocking found in setscrew mountings. These bearings ensure a high radial load capacity and use an extra barrier to prevent contamination, coming pre-sealed and greased for a prolonged lifespan. They include a tensioner stud for improved axial load handling and are adaptable for additional support with optional EXV thrust bearing units for extreme axial force requirements.

The 316 stainless steel double row spherical roller pillow block bearing from Extreme Bearing is engineered for challenging heavy-duty applications and environments prone to corrosion. Fabricated from grade 316 stainless steel, these bearing units are resilient to rust and chemical interactions, including seawater, ensuring durability and longevity. Featuring self-aligning double row ball bearings, these units provide quintuple the load capacity of standard models, focusing on optimal performance under vertical load conditions when supported over their entire base. These bearings come with enhanced sealing options, tailored to improve performance in demanding scenarios. Users must ensure the proper application, considering load direction and housing support, to maintain structural integrity and functionality. Extreme Bearing emphasizes the need for accurate product selection corresponding to real-world operating environments to maximize efficiency.

Radial oil seals, such as AS and SA seals, are essential for ensuring that bearing housings remain sealed against contaminants, thus prolonging their operational efficiency. These seals are specifically designed with rubber sealing lips, metal casings, and stainless steel garter springs, enhancing their durability and functionality. The AS seal is noted for its pressure-tight nature, which requires it to be paired with CS or CC seals, avoiding abrasion-prone environments. It aims to create a maintenance-free bearing unit while enabling air escape during initial greasing. Conversely, the SA seal features asymmetric lip angles that aid in preventing lubricant leakage and minimizing contaminants when used with grease. However, it is not suited for food applications due to potential contamination risks. For conditions involving abrasive materials, the CS design is recommended. The application of these seals with automatic lubricators can vastly enhance bearing lifespan by facilitating regular, minimal grease refilling to expel dust and moisture.

The CC and CL chemical resistant bearing seals are designed for challenging applications, particularly in harsh environments such as sea water, chemically corrosive conditions, or extreme temperatures. These seals incorporate a PTFE sealing lip and a stainless steel housing, offering robust resistance and durability. The CC type features external dual lips to flush out dirt and excess grease, thereby protecting the bearing housing from contaminants. Conversely, the CL type is maintenance-free, equipped with an additional lip to retain grease within, ensuring efficient operation without the need for frequent re-greasing. PTFE's properties provide a tight fit around the shaft, minimizing dirt infiltration, but care should be taken with abrasive contaminants. Proper shaft hardening in the seal contact area is recommended, with a minimum hardness of 45 HRC and potentially up to 60 HRC, to enhance performance and lifespan. While PTFE shows resistance to many chemicals, it is affected by certain substances under specific conditions.
