Enduro Bearings Deep Groove Angular Contact Ball Bearing MR/MRA 2437 24mm x 37mm x 7mm

Carefully manufactured, highly precise: the MR 2437 Bearing by Enduro Bearings

There is a choice of ABEC 3 deep groove ball bearings (type 1), ABEC 5 deep groove ball bearings (type 2) and angular contact ball bearings (type 3).

ABEC 3 bearings from Enduro Bearings feature 10th-degree chrome steel balls that are twice as round as the industry standard, and manufactured to the highest standard. The treads are made of a 52100 carbon chrome steel alloy that is vacuum-generated and then hardened for extra strength and durability. A high-gloss polish ensures precision and low noise.

ABEC 5 bearings from Enduro Bearings feature R64 hardened 5th degree chrome steel balls, making them suitable for high precision applications. They move in vacuum-formed treads made of 52100 carbon chrome steel, which are particularly resistant and durable. The nylon graphite ball bearing cages have virtually no friction, and ensure constant double-sided supply of Rheolube 374A grease.

In standard radial bearings, only 3 or 4 balls make contact during the load at any given time. Inside of Enduro Bearings' Angular Contact (A/C) bearings, ALL balls are engaged so that they can distribute force over a larger surface area. This reduces friction and minimizes wear.

Features:

Type 1:

• ABEC 3 bearings with riveted steel ball cage for more durability
• chrome steel balls 10th degree = circularity is 10/1,000,000"
• race grooves made of carbon-chrome steel alloy, heat and cold treated (down to -190° C), minimum hardness Rockwell HRC 62, polished
• LLB: widely used seal type made of nitrile rubber with steel insert, in a groove in the inner race (labyrinth bearing), two super thin sealing lips; the outer one keeps out water and contaminants, the inner one retains grease
• Level 3 in the rating of the Annular Bearing Engineer's Committee (ABEC) in terms of manufacturing tolerances and noise development

Type 2:

• Level 5 in the rating of the Annular Bearing Engineer's Committee (ABEC) in terms of manufacturing tolerances and noise development
• chrome steel balls 5th degree = roundness is 5/1,000,000"
• treads made of carbon chrome steel alloy, heat- and cold-treated (down to -190° C), hardness min. Rockwell HRC 62, high gloss polish for precision and quietness
• nylon graphite ball cage, grease supply on both sides
• SRS: Snap Ring Seal type that can be safely removed for quick and easy maintenance, simple sealing lip on a step milled into the inner tread, extremely low running resistance, effective barrier against dirt and water
• bearing clearance: C3

Type 3:

• Angular contact ball bearing with 15° angle
• Level 5 in the rating of the Annular Bearing Engineer's Committee (ABEC) in terms of manufacturing tolerances and noise development
• chrome steel balls 5th degree = roundness is 5/1,000,000"
• race grooves made of carbon chrome steel alloy, heat and triple cold treated (up to -190° C), hardness degree min. Rockwell HRC 62, high gloss polish for precision and quietness
• LLB: widely used seal type made of nitrile rubber with steel insert, in a groove in the inner race (labyrinth bearing), two super thin sealing lips; the outer one keeps out water and contaminants, the inner one retains grease
• 90% filled with waterproof high-pressure grease
• side with red seal is load side, 5-10 lbs pretension required
