Plate vibratory rammer/reversible plate compactor is mainly suitable for materials with less cohesion and friction between tamping particles, and is used in various backfill foundations, roads, squares, trenches and other compaction and asphalt and concrete pavement repair. In particular, it has a good tamping effect on non-sticky sandy gravel and gravel.

Lubrication plays a crucial role in the performance and longevity of SKF tapered roller bearings. When it comes to grease lubrication, common issues include uneven oil film distribution and poor appearance. Compared to oil lubrication, grease may offer less consistent performance and has a shorter lifespan. Therefore, high-quality grease with long-lasting properties is essential for optimal bearing function. In many cases, the service life of greased bearings is significantly shorter than that of oil-lubricated SKF tapered roller bearings.
In some countries, long-life greases are developed and used specifically for applications like boring spindles, where a thin, even layer of grease can last over 10 years. These specialized greases are also being researched and adopted domestically. When selecting the right lubricant, it's important to consider the operating conditions and choose a suitable type of grease. Proper lubrication intervals and removal cycles should be established based on the bearing’s environment and usage.
If the lubrication condition is not ideal, using high-quality grease along with an appropriate maintenance schedule is essential. Since the lifespan of grease can vary greatly, it's important to monitor and track the lubrication cycle over time. Once determined, under favorable environmental conditions, choosing the right seal can help maintain the effectiveness of the grease for a longer period. If the bearing’s service life requirements are not too demanding, one-time lubrication may be sufficient without the need for frequent re-lubrication—though this approach must be handled carefully.
Seals are vital for protecting SKF tapered roller bearings from contamination and preventing the loss of lubricants. A well-designed sealing system helps maintain the cleanliness and smooth operation of the bearing, contributing to its overall durability. However, the selection of seals should also take into account factors such as simplicity, cost, and the effectiveness of the sealing design. Choosing the right seal according to the application environment and requirements can significantly enhance bearing performance. On the other hand, improper use of seals, such as using contact seals at high speeds, can lead to excessive heat generation, rapid wear, and eventual failure of the seal. This can result in contamination of the bearing by wear particles. Non-contact seals, on the other hand, may experience pressure differences (air or oil pressure) that could compromise their sealing ability, leading to dust or oil ingress.
Adding extreme pressure additives and anti-wear agents to the lubricant can further improve the service life of SKF tapered roller bearings. These additives help reduce friction and wear, especially under heavy loads or high-speed conditions.
