LDS LPT (Low Pressure Table) slip tables are oil-film slip tables that give a cost-effective, general-purpose solution for horizontal vibration testing in most production line and research applications. They are suited to work where high stiffness and large payloads aren't required. Guidance bearings minimize axial distortion, and an oil film supports the load, with a tool-grade magnesium slip plate over a high-stability granite base in a rugged steel chassis. LPT tables come in standard sizes from LPT600 to LPT1220, stand-alone or combined with an LDS trunnion-mounted shaker as a complete combo system.
Bearing type: oil-fed journal guidance bearings, positioned on the center line
Configuration: stand-alone, or combo with LDS V721, V830, V850, V875, V875LS, and V8 shakers. Insert quantities are also defined for the V9 on the LPT1220.
Mobility: air-glide combination base available on all standard LPT combos
At a glance
Low-pressure oil-film bearings for cost-effective R&D and verification testing
Handles payloads up to 1,500 kg (3,307 lb) such as automotive assemblies
Sizes from 600 to 1220 mm, available stand-alone or as a combo system
Centre-line journal bearings need no adjustment for thermal expansion
Bearings
Center-line journal
Oil-fed journal guidance bearings sit on the center line, so there's no need to adjust for table expansion and contraction caused by thermal changes.
Application
General-purpose
A cost-effective solution for production line and research work that doesn't need HBT-level stiffness or payload capability.
Sizes
600 to 1,220 mm
Four standard sizes from LPT600 to LPT1220, with standard combos defined from the V721 up to the V8.
What it is used for
Some of the use cases for LDS LPT slip tables include:
Individual testing in three axes: pairing a trunnion-mounted shaker with a slip table for vertical and horizontal testing.
Production line testing: general-purpose horizontal vibration testing in production.
Automotive component testing: horizontal-axis testing of components and assemblies.
Electronic assembly testing: horizontal vibration screening and qualification.
Avionics and military hardware testing: horizontal testing of general payloads.
Packaging and transport testing: horizontal-axis transport and package simulation.
Center-line bearings: bearings sit on the center line, so there's no need to adjust for table expansion and contraction caused by thermal changes.
Oil film load support: a film of pressurized oil between the base and the plate gives uniform support across the surface and minimizes table rippling.
Tool-grade magnesium slip plate: chosen for high strength and light weight.
High-stability granite base: a thermally stable, precision-flat bearing surface.
Patented driver bars: shear pin and tension bolt driver bars.
Space-efficient design: minimizes floor area, with air-glide and castor mobility available.
Wide shaker compatibility: standard combos from the V721 up to the V8.
Why engineers pick it
Cost-effective horizontal testing. Good general-purpose performance for production and research work that doesn't need HBT-level stiffness.
No thermal adjustment. Center-line bearings remove the need to adjust for thermal expansion and contraction.
Combo alignment built in. In a combo, the Lin-E-Air body isolation and guidance system keeps the shaker body on the center line, minimizing distortion and maximizing low-frequency and payload capability.
Flexible layout. Order as a combo in one fabricated frame, or as a stand-alone table on a seismic base next to a trunnion-mounted shaker.
Combo systems versus stand-alone
LDS combo systems. For three-axis testing applications, we recommend the combo configuration. It offers easy installation and accurate alignment between shaker and table, reducing test setup time when switching from vertical to horizontal.
Stand-alone LPT slip tables. A trunnion-mounted shaker with a separate slip table on a seismic base is the favored arrangement for testing large or dynamically complex payloads, as it delivers optimal pitch, roll, and yaw restraint.
While it is possible to purchase a stand-alone slip table for retrofitting to an existing shaker, the combo option is preferable in most cases. Retrofitting is a more expensive, time-consuming endeavor that involves system downtime for installation and regular calibration, potential misalignment issues, and ongoing maintenance costs.
Choosing LPT or HBT
Choose LPT for general payload testing in production and research. Choose the LDS HBT series for exceptional payloads with a high center of gravity and high overturning moment, where higher stiffness, dynamic stability, and damping are required.
