Product description of TIMKEN Bearing JLM722948 - JLM722912-B

TIMKEN Bearing JLM722948 - JLM722912-B, Tapered Roller Bearings TSF (Tapered Single with Flange)Metric. Timken® tapered roller bearing assemblies are precisely designed to manage both radial and axial loads, even in the most unforgiving conditions.Double- or two-row Timken® tapered roller bearings feature double cups and two single cones. They are available in a variety of configurations for general industrial and automotive applications. And related type you may also like TIMKEN Bearing JM624649 - JM624610-B. TSF bearings have flanged cups to facilitate axial location and accurately align seals in through-bored housings.

TIMKEN Bearing JLM722948 - JLM722912-B, Tapered Roller Bearings TSF (Tapered Single with Flange)Metric. Each tapered roller bearing contains four interdependent components: the cone (inner ring), the cup (outer ring), tapered rollers (rolling elements) and the cage (roller retainer). Tapered angles allow our bearings to efficiently control a combination of radial and thrust loads. The steeper the outer ring angle, the greater ability the bearing has to handle thrust loads. To provide a true rolling motion of the rollers on the raceways, the extensions of the raceways and the tapered surfaces of the rollers come together at a common point, the apex, on the axis of rotation.

Extreme-pressure gear oils are used to lubricate Timken bearings in most types of heavily loaded industrial equipment. They should be capable of withstanding abnormal shock loads that are common in heavy-duty equipment.

Industrial EP gear oils should be composed of a highly refined petroleum oil-based stock plus appropriate inhibitors and additives. They should not contain materials that are corrosive or abrasive to bearings. The inhibitors should provide long-term protection from oxidation and protect the bearing from corrosion in the presence of moisture. The oils should resist foaming in service and have good water-separation properties. An EP additive protects against scoring under boundary-lubrication conditions. The viscosity grades suggested represent a wide range. High-temperature and/or slow-speed applications generally require the higher viscosity grades. Low temperatures and/or high speeds require the use of lower viscosity grades.
