25mm Long Base Pillow Block Bearing UCP205 for Fertilizer Machinery

25mm Long Base Pillow Block Bearing UCP205 for Fertilizer Machinery

GJP 25mm Long Base Pillow Block Bearing UCP 205 For Fertilizer Machinery with solid base housing. A ucp 205 bearing is essentially a metal housing with a bearing mounted inside. This type of bearing is popular because it is easy to install and is very affordable. Additionally, a pillow block bearing is very reliable and can last for years without needing any maintenance. UCP 205 pillow block bearing has compact structure, convenient loading and unloading, perfect sealing, suitable for simple support, often used in mining, metallurgy, agriculture, chemical industry, textile, printing and dyeing, conveying machinery, etc.

Product Details

Description-25mm metric Bore UCP 205 Pillow Block Bearing

GJP Bar Code Number: 6935329802117

GJP 25mm Long Base Pillow Block Bearing UCP 205 For Fertilizer Machinery with solid base housing. Which has grease zerk on 45 degree angle, and the insert bearing has a wide inner ring with two set screws for locking on the shaft, bearing insert and housing are normally assemblied with J7 tight fitting, this items are widely used.

The installation of the spherical pillow block bearing ucp 205:

  1. Before installing the bearing on the shaft, the fixing pin of the bearing jacket must be pulled out first, and the surface of the journal must be polished smooth and clean, and the journal should be oiled to prevent rust and lubricate (allow the bearing to rotate slightly on the shaft).
  2. Apply lubricating oil on the mating surface of the bearing seat and the bearing, and install the bearing into the bearing seat. Then put the assembled bearing on the shaft together with the bearing seat and push it to the desired position for installation.
  3. Do not tighten the bolts that fix the bearing seat first, so that the bearing shell can rotate in the bearing seat. Also install the bearing and seat on the other end of the same shaft, turn the shaft a few times, and let the bearing itself find the correct position automatically. Re-tighten the bearing housing bolts.
  4. Install eccentric sleeve. First put the eccentric sleeve on the eccentric step of the inner sleeve of the bearing, and tighten it in the direction of rotation of the shaft by hand, then insert the small iron rod into or against the countersunk hole on the eccentric sleeve, and tap the small iron rod in the direction of rotation of the shaft with a hand hammer. Iron rod to make the eccentric sleeve firmly installed, and finally lock the hexagon socket screw on the eccentric sleeve.

Design features of spherical ball bearing ucp 205:

The spherical ball bearing ucp 205 is actually a variant of the deep groove ball bearing. Although its basic performance should be similar to that of deep groove ball bearings, because these bearings are mostly used in relatively rough machinery, the installation and positioning are not accurate enough, the axis alignment between the shaft and the seat hole is poor, or the shaft is long and deflected. In the case of large and other, and the bearing itself is not high enough precision, and some structures are relatively rough, so the actual performance of the deep groove ball bearing of the same specification should be marked with a considerable discount.

The spherical ball bearing ucp 205 is mainly used to bear the combined radial and axial load mainly based on radial load. Generally, it is not suitable to bear the axial load alone. This kind of bearing can be installed with the inner ring (with a full set of rollers and retainers) and outer ring. The spherical ball bearing ucp 205 does not allow the shaft to be inclined relative to the housing, and additional axial force will be generated under the radial load. The size of the axial clearance of the  spherical ball bearing has a great relationship with whether the bearing can work normally. When the axial clearance is too small, the temperature rise is high; when the axial clearance is large, the bearing is easily damaged. Therefore, special attention should be paid to adjusting the axial clearance of the bearing during installation and operation. If necessary, pre-interference installation can be performed to increase the rigidity of the bearing.

Another feature of the spherical ball bearing ucp 205 compared with other ordinary bearings is the double-layer seal, because the general environmental conditions of the spherical ball bearing are harsh, especially for agricultural machinery bearings, and the double-layer seal ensures that the dust is not easy to enter the inside of the channel. As a china ucp 205 manufacturer, GJP’s pillow block bearings have enhanced dust resistance and extended bearing life.

Could customers send the engineers to inspect the cargo before shipment?

Yes, we welcome so much that customers send their engineers or any other third party personal inspectors or inspecting company come and inspect the cargo, GJP have been supplied some bearings to one UK Consultant company, this company purchase some bearings for the port equipment which requires DNV checking, During production they would pay lot of money and send DNV guy from Shanghai to get the material back to Shanghai for stamping DNV on the non-working parts in bearings, then when the bearings are ready for shipment, their engineers and DNV guy would come to our factory again to do the inspection, including the whole dimensions and technical data, and also the MT and UT testing, then after all approved, we release the shipment to customers.
