Trusted Difference at Every Turn TM PEER product validation and sealing solution Lab Testing / Mud Slurry Testing PEER´s Research and Development Center utilizes mud slurry testing to thoroughly study new seal concepts before extensive field tests are conducted to validate application performance. The test is performed to determine the effectiveness of the bearing sealing device to withstand contamination intrusion under aggressive environmental conditions. Seal designs are tested against competitive parts in side-by-side mud slurry testing. PEER sealing performance overview Seal...

Trusted Difference at Every Turn TM Tillage Bearings Soil preparation aims to provide best possible growing conditions in preparing a seedbed for crops by mechanical agitation of soil while at the same time preventing soil erosion and damage. Secondary tillage is typically performed in the following spring and is intended to reduce clod sizes, mix in crop residues and level the soil in preparation for seeding. Optimal soil conditions are defined by parameters such as soil density, size of soil particles and crop residue left on the field. Significant for all tillage procedures is to...

Application challenges The typical bearing speed of disc harrow tillage application is between 100 and 150 min-1. The bearings supporting these tillage discs essentially operate at or even partially below ground level. Moist or dry, abrasive contamination forcefully pushes against bearing faces and seals during operation. Independent disc application conditions • Utilizes one bearing assembly for each disc • High loads and constant unpredictable movement of the disc can generate severe stress on the internal components • A great working depth places the bearings directly into the flow of...

Trusted Difference at Every Turn TM Seedbed finisher application conditions • Utilizes two bearing assemblies • High misalignment from imprecise mounting and wide bearing spread attachments can generate severe stress on the internal components • Exposed directly into the flow of soil and crop residue PEER proven engineered system solutions Tillage flanged disc units (FD and RFD), Mounted units (UCF and UCFT) The most commonly used attachment bearing arrangements on a seedbed finishing tool are the FD and RFD units (flanged disc units), UCF and UCFT (mounted units). Mounted units (UCF and...
