Use Cases

Support equipment in compression

Use these mounts beneath equipment intended for compression mounting, including compressors, blowers, air-conditioning equipment, pumps, machine tools, and transformers.

How to Choose

Match the mount to the load

Start with the equipment load and select a mount within its stated load range or maximum load. Then confirm that the mount is designed for compression-only use and that its size works for the available installation area.

Applications

Help reduce transmitted vibration

Floor-mount neoprene isolators create a mounting point between equipment and the supporting floor. Compression vibration mounts are designed to help isolate vibration and noise from supported equipment.

Additional Information

Review mounting features

Many neoprene floor mounts include top bolts and washers for fastening equipment. Their friction-covered bases generally help keep the mount in place without bolting it to the supporting structure; selected neoprene options also provide oil-resistant construction.

Product Types

Compare neoprene floor isolators and compression vibration mounts

Neoprene floor-mount vibration isolators are compression-only mounts with a thicker profile and greater deflection than isolation pads. The listed floor-mount styles use friction-covered bottoms and commonly include top bolts and washers. Compression vibration mounts are also for compression-load applications and are offered with stated maximum loads, deflection, and double-deflection construction.

  • Neoprene floor isolators: friction-covered base and top mounting hardware on listed models
  • Compression vibration mounts: stated maximum load and deflection
  • Double-deflection mounts: axial and radial elasticity for vibration and noise isolation
Load and Size Planning

Confirm load range, maximum load, and footprint

Choose according to the supported equipment load. Listed neoprene isolators span load ranges from 15–45 lb through 310–600 lb, while listed compression vibration mounts have 25 lb and 225 lb maximum-load options. Where dimensions are provided, compare the mount length, width, and height with the available space beneath the equipment.

  • 15–45 lb, 40–75 lb, 75–150 lb, 110–235 lb, 300–600 lb, and 310–600 lb neoprene load ranges are represented
  • Listed compression vibration mount maximum loads: 25 lb and 225 lb
  • Listed floor-mount sizes include 3-3/16 x 1-5/8 x 1-1/2 in., 3-7/8 x 2-5/16 x 1-7/8 in., and 5-1/2 x 3-5/16 x 2-3/4 in.
Installation Considerations

Select for compression-only mounting

All represented products are designed for compression-only or compression-load applications. For floor-mount neoprene isolators, top bolts and washers help attach compatible equipment, while the friction bottom generally reduces the need to bolt the mount to the supporting structure. Review whether oil-resistant neoprene is needed for the equipment area.

  • Use only where equipment is supported in compression
  • Top bolts and washers are included on many listed floor-mount isolators
  • Friction-covered bases generally help hold floor mounts in place
  • Minimum order is one on the listed products that state a minimum order
FAQ

Common questions before buying

What equipment can compression mounts support?

The represented mounts are suited for compression-mounted compressors, blowers, air-conditioning equipment, pumps, machine tools, and transformers.

Are these mounts designed for tension applications?

No. The represented products are described for compression-only or compression-load mounting applications.

Do neoprene floor-mount isolators need to be bolted to the floor?

Their friction-covered bases generally help keep them in place without bolting the mount to the supporting structure.

How should I choose a load rating?

Match the mount to the supported equipment load using the stated load range or maximum load for the specific option.
