KOYO bearings installed, you should check ring and shaft centerline axis vertical. Method is to face dial indicator fixed on the tank shell, the head of the table to touch the bearing axis in the rotating bearing ring raceway on top, while observing dial gauge pointer, if the pointer deflection, indicating the ring axis and the axis is not perpendicular to the centerline. Tank shell hole deeper, the head can also use an extension of the dial gau...
Koyo Needle Roller Bearing
Needle roller bearings are small in sectional height, therefore useful in making machinery smaller and lighter. This type of bearing is used in a wide range of machinery, such as automobiles, motor cycles, electric machines, machine tools, aerospace and office equipment.
Compact, highly rigid and superior in load carrying performance, compared with other types of bearings.
Excellent for carrying oscillating loads; con...
Koyo Spherical Thrust Roller Bearing
Spherical thrust roller bearings are designed to carry high axial loads. They can also support radial load if magnitude is no more than 55% of the axial load being carried.
These bearings are not suitable for high-speed rotation.
Having a spherical housing washer raceway surface, these bearings are self-alignings, adjusting to axial inclination.
They are usually used with oil lubrication.
1. This type of bear...
Koyo Spherical Roller Bearing
Spherical roller bearings feature a large load rating and self-aligning capability
This type of bearing is suitable for low- or medium speed applications which involve heavy or impact loading.
These bearings are divided into R, RH(R) and RHA types, which differ in internal structure.
Each type can be produced with a cylindrical bore or tapered bore.
Bearings with a tapered bore can be fit and removed easily using a...
Koyo Tapered Roller Bearing
Tapered roller bearings are designed such that cup, cone and rollers have tapered surfaces whose apexes converge at a common point on the bearing axis.
Along with metric series bearings, inch series bearings are also available.
This type of bearing is suitable for applications that involve heavy or impact loading.
Single-row tapered roller bearings
Able to carry radial and axial load in one direction simultaneously.
B...
Koyo Cylindrical Roller Bearing
Cylindrical roller bearings feature high radial load capacity because the rollers and raceway are in linear contact. These bearings are suitable for applications that involve heavy radial and impact loading.
They are also appropriate for high-speed applications in that they can be machined very accurately due to their structure.
Having a separable inner ring or outer ring, these bearings can be mounted and dismount...
Koyo Thrust Ball Bearing
Thrust ball bearings are divided into single and double direction types. The former is able to accommodate axial load in one direction, while the latter is able to accommodate it in both directions.
Neither is suitable for applications that involve radial load or high-speed rotation.
ball Bearings whose housing washer back face is spherical (with a spherical back face or aligning seat washer) are designed with a self-alig...
Koyo Self-aligning Ball Bearing
Self-aligning ball bearings have a spherical outer ring raceway, the center of whose curvature meets that of the ball bearing itself, so that the inner ring, balls and cage continue to rotate, aligning themselves if they have become misaligned within design limits.
This type of bearing is suitable when the displacement of the centers around which the shaft and housing rotate and shaft deflection are likely to occur...
Koyo Angular Contact Ball Bearing
Angular contact ball bearings are suitable for applications which require high accuracy and good high-speed performance. This type of bearing is designed to carry a combined load.
Single-row angular contact ball bearings and matched pair angular contact ball bearings
The standard contact angles are 15,30 and 40.
They are identified, respectively, by the supplementary codes "C", "A"(omitted) and "B". Bearings wi...
Koyo Deep Groove Ball Bearing
Deep groove ball bearings are available in a variety of sizes, and are the most popular of all rolling bearings. This type of bearing supports radial load and a certain degree of axial load in both directions simultaneously.
Shielded/sealed type
Simplifies sealing structure of applications.
Greasing is not necessary because bearings are pre-lubricated.
With locating snap ring
Bearings with a locating snap ring can ...
