Construction

The TANN mounted bearing unit is a bearing unit that combines the spherical outside surface ball bearing, seal, and housing of high-grade cast iron or pressed steel. It features a variety of structure patterns, & is suitable for application under tough conditions. 

The outer surface of the bearing and the internal surface of the housing are spherical so that the unit is self-aligning. Set-screw locking is the most popular method of mounting to the shaft. Adapter sleeve and eccentric locking collar are also available. For service under more severe operating conditions, Bearing units with cast iron covers and pressed steel covers and or in plastic are available as standard types.

The covers are constructed in such a way as to guarantee even eventual substitution of rubber seals with commonly felt rings. There are also closed covers used in applications where the shaft does not pass.

The outside diameter of the self-contained bearing's ground is spherical to match the corresponding spherical inside diameter of the housing providing self-alignment between these two parts, which compensates for misalignments of the units re- resulting from errors in mounting and distortion of the foundation.

Features of Bearing Units

UCP 201-212 Pillow block bearing units are easy to mount widely used in transportation machinery, mines, metallurgy, reaper, textile machinery, bodybuilding equipment, motors, chain belts, chain wheels, and automobiles, etc. The insert bearings correspond to 62 series deep groove ball bearing, it is with the same structure, but has wider inner rings. The bearing insert is well protected and can compensate for alignment defects thanks to its spherical outer ring. If necessary it can be replaced very easily. The cast iron housing has a grease nipple for re-lubrication.

Rational self-alignment

Larger load carrying capacity, relubricable, longer service life of the units

Efficient, sealing ability of the units with covers is perfect

Solid housing, provide maximum rigidity against deformation for any condition

Easy and positive locking to shaft

Special heat-treatment on bearing inner ring prevent causing cracking

Unique device to prevent bearing outer ring rotation

Complete interchangeability between bearing and housing

Easy installation

Easy positioning for mounting

Applications

Agricultrue, mining, engineering, chemical machinery, textile, plastic, dyeing and fining, and other industries

Materials

The performance and reliability of rolling bearings are greatly affected by the materials which the bearing components are made from TANN  bearing rings and balls are made of high quality of Gcr15 (100cr6) - type of bearing steel and the chemical composition is shown as below.

Chemical composition of high-carbon chrome bearing steel:

Standard steel material
		C	Si	Mn	Cr	Mo	P	S
DIN	100Cr6	0.95~1.05	0.15~0.35	0.25~0.45	1.40~1.65		≤0.030	≤0.025
JIS	SUJ2	0.95~1.10	0.15~0.35	≤0.50	1.30~1.60		≤0.025	≤0.025
GB/T	Gcr15	0.95~1.05	0.15~0.35	0.25~0.45	1.40~1.65	≤0.08	≤0.025	≤0.025
ASTM	52100	0.98~1.10	0.15~0.35	≤0.50	1.30~1.60		≤0.025	≤0.025

Most of ball-bearing cages are made of cold-rolled steel sheet. And for some bearing types and special applications, cages are made of glass fiber reinforced nylon 66 plastic, phenolic or machined brass.

The material of bearing housings is gray or ductile cast iron, housings can also be made of pressed steel, stainless steel, or engineering plastic for special purposes, depending on application and or customer's requirement. 

Mechanical properties of housing material:

Class	Thickness	Diameter	Tensile strenght	Bender	Deflection	Pressure	Hardness
	mm	mm	kgf/mm²	kgf/mm²	mm	kgf/mm²	HB
HT200	< 06-80	13	< 32	53	1.8	75	187-255
	< 08-15	20	< 25	45	2.5	75	170-241
	< 15-30	30	< 20	40	2.5	75	170-241
	< 30-50	45	< 18	34	3	75	170-241
	< 50	60	< 16	31	4.5	75	160-229

TANN uses gray cast iron as the standard material for cast iron housings. Among metallic material cast iron has a high damping capacity, which is an ideal characteristic for mechanical components. This means cast iron, exhibits superior performance when absorbing vibration, compared with other materials. Additionally cast iron is suitable for high temperatures of up to 300C°.

In order to maintain the quality constant over time, below entire series of tests reported are performed:

- hardness tests on the materials

- microscopic inspection

- chemical analysis of the composition

- magnetic exploration

- corrosion from contct with acid substances

- noise and vibration tests

- visual inspection

*Further requires please feel free to contact Stacy

Lubrication of Bearing Units

The bearing units are all grease-lubricated and are basically to be relubricated. The grease injected from the grease fitting by means of a grease gun flows into the bearing chamber passing through the grease groove in the housing & grease hole in the bearing outer ring. 

For relubrication, it is recommended to supply the grease during opethe ration of Bearing units so as to avoid excessive greasing.

As the bearings are to be operated for ratha er long time without supplement of grease, the grease must be of high quality. 

When selecting the grease, care must be taken not to use improper grease as there are various types of grease available by mixing mineral oil and metallic scope base according to the application purpose. 

There are below types of the grease fittings available as shown:

Standard type

45° fitting

90° fitting
