How to quote ROLLWAY bearings: types, uses and data to order by code

ROLLWAY is a bearing brand. To quote ROLLWAY bearings at MR, the first thing is to know what type of bearing you need: deep groove ball, cylindrical roller or tapered roller. Each type supports different loads and speeds depending on the equipment where it is mounted.

Deep groove ball bearings are the most common in electric motors, pumps and gearboxes. They support moderate radial and axial loads, and can have seals or metal shields as needed. Cylindrical roller bearings, on the other hand, are designed for heavy radial loads.

Tapered roller bearings combine radial and axial load in one direction, which is why they are used in gearboxes and wheels of mobile equipment. When quoting, it is best to indicate the full code and the dimensions if it is not legible. You can also send a photo of the part so we can help you identify it.

Deep groove ball bearings are versatile and are mounted in a wide variety of machines. They appear in electric motors, fans, centrifugal pumps and machine tools. Their simple design allows high speeds and easy maintenance.

To identify them, look at the code engraved on the side face. Among the usual suffixes, 2RS indicates rubber seal on both sides, 2Z indicates metal shields and C3 indicates an internal clearance greater than normal.

When requesting a quote, send us the full code and the ROLLWAY brand. If it cannot be read, measure the inner diameter, outer diameter and width with a caliper. With that data we help you identify the bearing. Avoid ordering only by dimensions because there may be seal or internal clearance variants.

Cylindrical roller bearings are made to withstand high radial loads. They are used in large motors, gearboxes and heavy equipment. In some designs the inner or outer ring can be removed separately.

These bearings are identified with a letter prefix followed by numbers, and the letters indicate the arrangement of the ring flanges. That is why it is best to pass the full code exactly as engraved, without shortening it.

To quote, we need the full code and, if possible, a photo of the part. It also helps to know what equipment it came from and what brand it originally had. Replacing a cylindrical roller bearing with a ball bearing without reviewing the loads is not advisable, because it can fail earlier.

Tapered roller bearings support combined radial and axial loads. They are common in gearboxes, wheels of industrial vehicles, pumps and agricultural machines. They are mounted in facing pairs or back-to-back depending on the application.

The contact angle and the number of rollers vary by series, which is why the full code is key when quoting.

When requesting a quote, indicate the code and whether the bearing works with another identical one on the same shaft. It also helps to know whether it has a sheet steel or polymer cage. If you do not have the code, measure the inner diameter, outer diameter and total width, and send us a photo.

Identifying a ROLLWAY bearing is simple if the code is legible. Look for the engraving on the side face or on the edge of the outer ring. The full code includes numbers and letters that indicate type, size and variants such as seals or internal clearance.

If the code is erased, you can measure the main dimensions with a caliper. Note the inner diameter, outer diameter and width in millimeters. With that data and a photo, at MR we help you find the bearing you are looking for.

It also helps to know what machine it came from and what brand it originally had. Many times the equipment manual lists the exact bearing. Avoid ordering only by dimensions because there may be differences in seal, cage or precision that affect operation.

One of the most common mistakes is ordering a bearing only by dimensions without considering the type of seal. An open bearing is not the same as one with rubber seals (2RS). The seal protects against contamination and retains grease, and changes performance.

Another mistake is not checking the internal clearance. A bearing with C3 clearance is used in applications with heat or tight fits. If you mount one with normal clearance under those conditions, it can seize and fail prematurely.

When mounting, use suitable tools and never strike directly on the rings. Heat the bearing if the fit is tight, but without exceeding temperatures that damage the grease or seals. If you have doubts, consult us before installing to avoid damage.

To quote ROLLWAY bearings, write to us by WhatsApp or email with the full code. If you do not have the code, send the dimensions and a photo of the part. Also indicate the quantity and the application where it is mounted.

MR is in Buenos Aires, Argentina, and quotes ROLLWAY bearings promptly. We handle maintenance orders of any size.

If your current bearing is from another brand, send us the code and we will review it. We send you the quote through the same channel you wrote to us on.
