The MBA Aerostar Turbo Cross-Shaft (TCS) Bearing Block Kit is designed to save time and reduce maintenance with long-life polymer bearings. These advanced technology bearings eliminate premature wear of the cross-shaft and last longer than the OEM solution.
Exhaust pressure pulses from the engine cause oscillations at the turbo’s wastegate butterfly resulting in vibration at the cross-shaft bearing blocks and lead to premature wear of the bearings and end shafts. With high-temperature self-lubricating polymer bearings securely carrying the turbo cross-shaft at both ends, without the need for any lubrication, premature wear is eliminated and maintenance is reduced saving you time and keeping you flying longer. |
