use in elastic mounting applications involving free-standing generators as well as other industrial machinery, these O Mount options offered to come with advantages of providing insulating support to the noise generated as well as dampening of the vibrations. Other than generators, these O mounts are also suitable to be used for machines like stationary diesel engines and emergency power units among others. Further, these also offer support to the needs of height adjustment that allows optimum levelling of the generator. Other than this, the stop provision provided with mounts also allows safe transmission of tensile stress in case of short circuit. Our expertise lies in also developing custom mounts to meet demands of specific machinery system.

Description

Cylindrical Mounts (O Mounts) – Versatile Rubber Vibration Isolators

Overview

Cylindrical mounts, also known as O mounts or bobbin mounts, are simple yet effective rubber vibration isolators consisting of a cylindrical rubber element bonded between two metal plates with threaded studs. The design provides vibration isolation in compression, tension and shear, making them suitable for a wide variety of applications.

Features

  • Simple cylindrical rubber-metal bonded construction
  • Dual-stud design allows compression and tension loading
  • Isolation in multiple directions (compression, tension, shear)
  • Compact and lightweight design
  • Cost-effective vibration isolation solution
  • Available in numerous sizes and rubber hardness grades
  • Standard metric and imperial stud threads

Applications

Cylindrical O mounts are used in:

  • Industrial machinery and workshop equipment
  • Small pumps, fans and motors
  • Automotive and vehicle applications
  • Electronic equipment and control panels
  • HVAC equipment and small air handling units
  • Laboratory and medical equipment
  • Marine and transportation vibration isolation

Technical Specifications

  • Material: Natural rubber
  • Stud Types: Male-male, male-female, female-female
  • Standard Sizes: 15mm to 100mm diameter, 10mm to 120mm height
  • Load Range: 5 kg to 150 kg per mount

Common Mounting Configurations

Male-Male (Type 1):

Threaded studs on both sides, equipment bolts from top, base bolts from bottom.

Male-Female (Type 2):

One threaded stud, one threaded insert. Provides different mounting flexibility.

Female-Female (Type 3):

Threaded inserts on both sides. Bolts thread into mount from both directions.

Benefits

  • Versatile mounting options for various configurations
  • Good vibration isolation for light to medium loads
  • Resistant to oils, chemicals and weathering
  • Easy to install and replace
  • Wide selection of sizes and load capacities
  • Can be used in compression or tension
  • Long service life with minimal maintenance

Selection Guidelines

Choose cylindrical O mounts based on:

  • Equipment weight and number of mounting points
  • Type of vibration (frequency and amplitude)
  • Operating environment (temperature, chemicals)
  • Mounting configuration (space constraints)
  • Rubber hardness for required deflection
