VL R series V-ring seals are V-shaped lip rotary seals that mount on the shaft and seal against a perpendicular face. Their elastic design makes them ideal for protecting bearings and gearbox housings against dust, water and splashes, even in applications where the shaft rotates at high speed. At MR Accesorios Industriales we carry them as part of our line of seals and oil seals for industrial maintenance.
The designation of these seals combines a number indicating the nominal shaft diameter, followed by the letters VL R. For example, 140 VL R, 150 VL R and 160 VL R correspond to shafts of 140, 150 and 160 mm respectively. The letters VL identify the profile geometry, and the final R distinguishes the compound and hardness variant. The higher the number, the larger the shaft diameter for which the seal is intended.
They are used in pumps, electric motors, gearboxes, conveyor rollers and process equipment. In Argentine industry they appear in food, paper, cement plants and in the oil & gas sector, where sealing against external contaminants is critical. They are also installed as secondary protection ahead of radial shaft seals, extending bearing service life.
To select the correct seal, check the shaft diameter and the permissible peripheral speed. Installation is done by pressing it onto the shaft, without the need to disassemble the bearing, and the lip must rest on a machined perpendicular face. Lubricating the lip with compatible grease before mounting improves sealing and reduces wear. Proper shaft alignment prevents premature leaks.
Regarding interchangeability, V-rings are identified by their diameter and profile, so different brands offer dimensional equivalents. It is always advisable to verify the compound and temperature range before replacing one seal with another. If you have doubts, send us the complete part number and operating conditions via WhatsApp and we will advise you.

Frequently Asked Questions
- How do I choose the correct size of a VL R V-ring seal?
- Measure the shaft diameter where the seal is mounted and choose the matching number. For example, a 150 mm shaft uses
150 VL R. If the shaft is worn, consult us via WhatsApp before deciding on the size. - Can they be mounted without disassembling the bearing?
- Yes, the V-ring stretches and is placed over the shaft without the need to disassemble the bearing. This simplifies maintenance and reduces downtime on industrial equipment.
- What is the difference between a V-ring and a radial shaft seal?
- The V-ring seals against a perpendicular face and does not require machining of the housing, while the radial shaft seal seals against the shaft and requires a housing. They are often combined to improve protection.
