This is the genuine Davey replacement motor shaft bearing (part no. 48997) for the complete Silensor and SilensorPro pump range. A double-sealed, deep groove ball bearing, it supports the motor rotor shaft, enabling smooth, low-friction rotation during pump operation. It is typically replaced when a pump develops abnormal noise, vibration, or bearing seizure due to wear over time.<\/p>\n
Davey specifies this single bearing part for all SLS and SLL Silensor models, including the SLS100, SLS150, SLS200, SLS300, SLL150, SLL200, SLL300, and SLL400. It also applies to the SilensorPro variable-speed pump series. Because one part number covers the entire range, there is no need to identify a specific sub-model before ordering.<\/p>\n
Sourced directly through Davey’s European parts programme, this bearing carries the correct C3 internal clearance rating \u2014 designed for high-speed, elevated-temperature electric motor applications \u2014 and the double rubber (2RS) sealing required to keep pool-environment contaminants out and grease in. Using a generic substitute without the C3 specification risks premature wear and increased noise in a pump motor running at sustained high speed.<\/p>\n
Bearing replacement requires full motor disassembly, including rotor removal. The task is best carried out by a qualified pool technician or motor service engineer with appropriate pressing tools. Davey’s Silensor servicing instructions (available from Davey Europe) provide step-by-step guidance for safe disassembly and reassembly.<\/p>","protected":false},"excerpt":{"rendered":"
