Bearing rollers are one of the elements used in industrial and mechanical units inside bearings. Rollers rolling along the rolling track are separated by spacers for equal distribution and movement. Rollers are made of carbon chrome steel and help the bearings withstand certain loads depending on the type and location.
Cylindrical bearing rollers
(Rollers for bearings and their arrangement)
Rollers for bearings are divided into: cylindrical, needle, conical and spherical. Therefore, the bearings get their name depending on what shape the rollers are placed inside.
Types and areas of application of rollers for bearings.
Cylindrical
They have the shape of a cylinder, which is why they got that name. They are made of high-carbon bearing steel, for example, of structural bearing steel — ShX15 or ShX15SG. Properties of steels allow to install rollers in bearings used for high radial loads and low rotation speed. Cylindrical rollers differ in shape, size, degree of accuracy and quality of contact surfaces.
Short cylindrical roller

Long cylindrical roller
Long cylindrical roller
(Long and short cylindrical rollers:
D is the nominal diameter;
L is the nominal length.)
They produce 2 types of cylindrical rollers for bearings:
short rollers, their length is less than twice the diameter (L< 2D) with a hardness of 61 — 66 HRC, manufactured with six degrees of accuracy in accordance with the GOST 22696 standard;
the rollers are long, their length exceeds twice the diameter of the roller (L>2D) with a hardness of 60 — 65 HRC, having three degrees of accuracy.
The degree of accuracy reflects the correspondence of the deviations of various values (deflections of the length of the rollers, different sizes in diameter, etc.) of the cylindrical rollers when sorting the indicated data.(//tractor-service.com)
Long rollers have three degrees of accuracy, denoted by Roman numerals I; II and III in order of decreasing accuracy. That. I — the degree of accuracy with the smallest deviations from the dimensions and shapes of the rollers II — the degree with slightly larger deviations than I, III — the lowest degree of accuracy, as it allows the largest deviation from the dimensions.
Tables of the maximum deflection sizes, deflection shapes and arrangement of surfaces, as well as the roughness of roller surfaces are presented below.
The assigned degree of accuracy of the rolling element depends on its size and shape compliance with GOST. Short rolling elements are most in demand in bearings used in the production of vehicles, in metallurgy, in heavy engineering and other similar fields.
Conical
Their special location to the axis of rotation of the bearing makes it possible to withstand a combination of loads: axial and radial. They are made of high-quality (high-carbon bearing steel with increased purity) with a reduced content of oxygen and chemical inclusions. Depending on the application, rollers in conical bearings can be arranged in different ways.
Conical roller
Conical roller
(D is the nominal diameter;
D2 is the second diameter;
L is the nominal length.)
The images presented above show the single-row and double-row arrangement of rollers used in bearings for helical mechanical gears, for equipment and mechanisms, for metallurgical machines or in the arrangement of hand-held power tools, etc.
The ability to manufacture bearings with the choice of placement of conical rollers in them allows to increase their resistance to shock loads, wear and tear, and reliable service life.
With particularly high loads on the mechanisms, the tension remains low due to the geometry of the rolling elements and their distribution. The tight arrangement of the spherical rollers and rolling tracks allows you to evenly distribute the load on the bearings while maintaining the high load capacity of the nodes. Such a property allows extended use.
All permissible deviations of sizes and shapes for spherical rollers are regulated by GOST, as well as for others.
Persistent.
Rolling bearing support bodies together with bearing rings constantly experience certain loads. In cases where large axial loads are applied to industrial units, thrust roller bearings are used. The role of thrust rollers is performed by: cylindrical, conical and sphero-conical rollers.
Location of thrust rollers
Thrust bearings with cylindrical rollers are installed under the influence of low speeds, but large loads in the mechanisms.
Bearings with sphero-conical thrust rollers are capable of withstanding large radial and axial loads, and also have the properties of self-adjustment.
Thrust roller is used in bearings for small mechanisms: in truck suspensions, hydraulic boosters and other structures.
